THOMAS BRITTON, APPELLANT 

 

V. 

 

THE STATE OF TEXAS, APPELLEE 

 

On Appeal from the Criminal District Court No. 3 

Tarrant County, Texas 

Trial Court No. 1484193D (Counts I & II), Honorable Robb Catalano, Presiding 

 

May 21, 2019 

 

MEMORANDUM OPINION

 

Before QUINN, C.J., and CAMPBELL and PARKER, JJ. 

Thomas Britton (appellant) appeals his convictions for criminal mischief and arson. 

The convictions arose from vandalism done to a church. Included in the damage were

instances of broken stained glass, strewn furniture, and a burned kitchen. Appellant’s 

multiple issues on appeal cover two general areas. One concerns the exclusion of 
2

evidence of his supposed “bizarre” behavior and the other involves his competency. We 

affirm.1

Exclusion of Evidence

Appellant initially contends that the trial court erred in sustaining a particular 

objection by the State. Defense counsel was cross-examining a witness about his client’s 

change in behavior. Such change began around a month before the incident underlying 

his prosecution. The witness testified that the “most disturbing” instance of change she 

saw was appellant walking around with a cell phone “held very closely to his mouth.”

Defense counsel began to ask another question when the State objected “to [the]

relevance to this line of questioning.” In response, defense counsel alluded to appellant’s 

“bizarre” behavior and said, “we’re trying to determine when it started and if, in fact,

[appellant] was at the scene like evidence may or may not indicate, then why.” The trial 

court sustained the objection and allegedly erred in so ruling. We overrule the issue.

To preserve error relating to the impermissible exclusion of evidence, a 

complainant is obligated to make an offer of proof. That is, error cannot be founded on a 

ruling that excludes evidence unless a substantial right of the complainant was affected,

and the substance of the evidence was made known to the court by offer or was apparent 

from the context within which questions were asked. Mays v. State, 285 S.W.3d 884,

889-90 (Tex. Crim. App. 2009). Here, appellant informed the trial court of why he believed 

the excluded evidence was relevant. However, he did not inform the court of what the

its precedent when available in the event of a conflict between the precedents of that court and this Court.

a topic we need address.

evidence was. See id. (stating that an offer of proof “may consist of a concise statement 

by counsel, or it may be in question-and-answer form”). His burden included the task of 

proffering, with some degree of specificity, the substantive evidence he intended to 

present. Id. at 890 (discussing Warner v. State, 969 S.W.2d 1, 2 (Tex. Crim. App. 1998));

accord Kamanga v. State, 502 S.W.3d 871, 877 (Tex. App.—Fort Worth 2016, pet. ref’d) 

(stating that if appellant attempts to satisfy the requirement by a concise statement, that 

statement must include a summary of the evidence to be offered). Having failed in that 

regard, his purported error went unpreserved. Mays, 285 S.W.3d at 889-90; State v. 

Viernes, No. 07-18-00236-CR, 2018 Tex. App. LEXIS 9385, at *5-6 (Tex. App.—Amarillo 

Nov. 16, 2018, no pet.) (mem. op. not designated for publication) (concluding that the 

issue was not preserved because the State failed to identify the witness being excluded 

or the substance of his testimony).

Competency to Stand Trial

Next, we address appellant’s competency issues. He contends that:

[t]he trial court erred in not conducting a hearing on 

Appellant’s competency to stand trial in accordance with 

article 46B.004 of the Texas Code of Criminal Procedure. The 

trial court also erred in not impaneling a jury to determine 

Appellant’s competency in accordance with article 46B.005(b) 

of the Texas Code of Criminal Procedure. Finally, the trial 

court violated Appellant’s federal and state due process rights 

by failing to inquire into his competency to stand trial.

We interpret the contention as a multi-tiered attack. The first tier encompasses the 

trial court’s purported failure to sua sponte undertake an informal inquiry into appellant’s 

competency to stand trial. The second level concerns a sua sponte failure to convene a 

jury trial to formally adjudicate competence once an informal inquiry was completed. And,
4

because neither occurred, he allegedly was denied his right to due process. We overrule 

the issue.

Our analysis begins with the observation that a defendant is presumed to be 

competent to stand trial until proven otherwise by a preponderance of the evidence. TEX.

CODE CRIM. PROC. ANN. art. 46B.003(b) (West 2018). Furthermore, incompetency arises 

when the defendant lacks 1) the sufficient present ability to consult with his lawyer with a 

reasonable degree of rational understanding or 2) a rational as well as factual 

understanding of the proceedings against him. Boyett v. State, 545 S.W.3d 556, 563

(Tex. Crim. App. 2018). 

Next, either a party or the trial court, sua sponte, may suggest that a defendant is 

incompetent. TEX. CODE CRIM. PROC. ANN. art. 46B.004(a) & (b). Yet, “[i]f evidence 

suggesting the defendant may be incompetent to stand trial comes to the attention of the 

court, the court on its own motion shall suggest that the defendant may be incompetent 

to stand trial.” Id. art. 46B.004(b) (emphasis added); accord Staples v. State, No. 05-18-

00177-CR, 2018 Tex. App. LEXIS 10096, at *3 (Tex. App—Dallas Dec. 7, 2018, no pet.) 

(mem. op., not designated for publication) (stating that the initial inquiry is informal and is 

required “only if evidence suggesting incompetency comes to the trial court’s attention”). 

And, “[o]n suggestion that the defendant may be incompetent,” then the court must 

undertake an informal inquiry to assess whether there is some evidence from any source 

that would support a finding of incompetency. Id. art. 46B.004(c). That inquiry may 

consist of little more than the trial court posing questions to both the defendant and/or

defense counsel. Staples v. State, 2018 Tex. App. LEXIS 10096, at *21; White v. State,

No. 02-12-00087-CR, 2013 Tex. App. LEXIS 10369, at *4 (Tex. App.—Fort Worth Aug.

15, 2013, no pet.) (per curiam) (mem. op., not designated for publication); Coyt-Sowells

v. State, No. 14-11-00986-CR, 2013 Tex. App. LEXIS 4612, at *3 (Tex. App.—Houston 

[14th Dist.] Apr. 11, 2013, no pet.) (mem. op., not designated for publication). Exhaustive 

inquisitions are unnecessary. White, 2013 Tex. App. LEXIS 10369, at *4; Coyt-Sowells,

2013 Tex. App. LEXIS 4612, at *3. 

In the event an informal inquiry reveals “some evidence” of incompetency, then the 

issue undergoes further analysis via formal inquiry or jury trial. Boyett, 545 S.W.3d at 

563. “Some evidence” means more than a scintilla from which one may rationally deem 

the accused incompetent. Id. at 563-64. That is, there must be some evidence from 

which it may rationally be inferred 1) that the defendant suffers some degree of debilitating 

mental illness, 2) that he obstinately refuses to cooperate with counsel to his own 

apparent detriment, and 3) that his mental illness is what fuels his obstinacy. Id. at 564. 

And, when assessing whether such a quantum exists, the trial court only considers 

evidence of incompetency; evidence of competency is ignored. Id. We finally note 

various observations made by our Court of Criminal Appeals in discussing these three 

components. As it said in Boyett, it “is not enough to present evidence of either a 

defendant’s mental illness alone or his refusal to cooperate with counsel—rather, there 

must be some evidence indicating that the defendant’s refusal to rationally engage with 

counsel is caused by his mental illness.” Boyett, 545 S.W.3d at 564. Nor is it enough if 

there is some evidence of 1) mental illness without accompanying evidence from which 

one may reasonably infer that the defendant’s mental illness renders him incapable of 

consulting rationally with counsel, 2) refusal to cooperate with counsel without evidence 

that the obstinance is fueled by mental illness, or 3) mental illness and obstinance but no 
6

rational basis to infer that the latter is the product of the former. Turner v. State, 422 

S.W.3d 676, 696 (Tex. Crim. App. 2013). 

Here, the trial court at least twice ordered appellant to undergo mental examination

by an expert to assess appellant’s competency. The most recent evaluation occurred 

several days before trial began. When the parties appeared at trial to select a jury, the 

trial court asked counsel for appellant whether his client was competent. Defense counsel 

answered: “According to Dr. Norman, yes.” At the very least, those examinations 

satisfied the definition of an informal inquiry into appellant’s competence. Yet, appellant 

believed himself entitled to another informal inquiry once he appeared on the witness 

stand to testify on his own behalf during the guilt / innocence phase of the trial. When 

doing so, he uttered various statements allegedly suggesting incompetence. Those 

statements consisted of replies touching upon his military background, reasons for being 

at the church, and attitude toward the prosecutor. We allude to them now. 

Appellant was once a United States Marine who believed that “[o]nce a Marine,

always a Marine.” So, continuing to be a Marine, he told his attorney during direct 

examination that he could “not confirm or deny” how long he was a Marine.

3

As one still in the Marines, he also felt a continuing obligation to thwart terrorism. 

So, when asked by his defense attorney why he was at the church on the day of the 

vandalism, he indicated it was to encounter a radical who intended to shoot police and 

“to fire a warning shot across the bough [sic] of these rogue elements in church and state 

that we are heading towards genocide.” So too did he explain that his actions were

justifiable because “[i]t was [his] duty to save . . . fellow citizens from . . . ego maniacs

 

3 Eventually, appellant conceded that he was in the Marine Corps for 3.5 years.
7

[sic].” “To protect the innocent from slaughter is duty, whether or not people understand 

or not,” he continued. 

This theme about remaining a Marine and, therefore, obligated to protect “fellow 

citizens” continued during the State’s effort to cross-examine him. Appellant felt that the 

prosecutor was being rude, unkind, bullying, and badgering. And, characterizing himself 

as “a prisoner of war,” he threatened to invoke his rights under the “Geneva Convention”

and only provide his name, rank, and serial number if the badgering did not stop. 

The foregoing litany of answers provided the basis for his argument on appeal. 

Their tenor constituted some evidence of incompetence, in his view. 

Again, one is incompetent to stand trial when unable to consult with his counsel 

with a reasonable degree of rational understanding or when he lacks a rational or factual 

understanding of the proceedings against the person. Implicit in these tests is a 

combination of mental illness and obstinance or inability to cooperate with defense 

counsel due to that illness, as indicated in Boyett. In viewing the aforementioned litany 

of answers, the trial court reasonably could have viewed them as evidence of only one of 

the two Boyett elements. That is, it could have viewed them as some evidence of mental 

illness. 

That appellant believed his mantra of “once a marine, always a marine” required 

him to engage in destructive behavior within the church may be irrational and derivative 

of mental illness. And, the trial court could well have deemed it so. On the other hand,

the trial court was privy to appellant’s demeanor during questioning and his answers to 

the questions propounded by his attorney. It could have viewed that demeanor and those 

answers as depicting someone quite capable of articulating beliefs and explaining the 
8

reasons underlying his actions. It could have viewed them as illustrating a general 

understanding of the questions being posed to him by defense counsel, a willingness to

answer them, and an ability to formulate answers. This differs greatly from the situation

in Turner wherein Turner refused to cooperate with defense counsel and believed counsel 

to be acting against his (Turner’s) interests. Here, appellant even characterized his 

attorney as a “good wing man.”

4

 

We must remember that mental illness without evidence of obstinance or an 

inability to consult rationally with counsel falls short of incompetence, per Turner. 

Appellant was able and willing to cooperate with his attorney, or so the trial court could 

have reasonably concluded, despite potentially suffering from a mental illness. Indeed,

there is a difference between uttering answers which could be viewed as irrationally 

founded and uttering answers or engaging in conduct depicting an inability to rationally 

consult with legal counsel. See Ross v. State, 133 S.W.3d 618, 629 (Tex. Crim. App. 

2004) (observing that “[a]ppellant’s statements to his mother and to co-counsel ‘which 

suggest some irrationality’ and appellant not wanting to have witnesses called on his 

behalf at the punishment phase do not necessarily show appellant’s inability to rationally 

consult with his lawyers or to understand the proceedings against him”). The former is 

not necessarily evidence of incompetence while the latter is. So, while appellant’s 

reasons for doing what he did in the church building may be irrational to someone hearing 

them, their lacking rational basis does not equate an inability to consult with counsel in a 

rational way. Given this and because a “trial court’s first-hand, factual assessment of a 

 

4 This happened when appellant investigated the possibility of representing himself with the aid of 

trial counsel. He decided against pursuing the option once the trial court questioned him about it. Yet,

even in the give-and-take between the trial court and appellant as the option was explored, appellant 

illustrated no hostility toward or refusal to cooperate with his attorney. 
9

defendant’s competency is entitled to great deference on appeal,” Staples, 2018 Tex. 

App. LEXIS 10096, at *3, we cannot say that the trial court abused its discretion in

forgoing a sua sponte, yet, informal inquiry into appellant’s competency.5 See Alexander 

v. State, No.13-96-505-CR, 1997 Tex. App. LEXIS 6131, at *12-13 (Tex. App.—Corpus 

Christi Nov. 26, 1997, pet. ref’d) (not designated for publication) (wherein appellant’s 

ability to communicate articulately, coherently, and responsively with those around him 

despite having an alleged mental illness were factors indicative of competence to stand 

trial).

The same is true of forgoing a formal trial on competency. We find no evidence of 

a refusal to cooperate with defense counsel due to a mental illness. So, neither Turner

nor Boyett mandated a subsequent, formal adjudication of appellant’s competency. And,

this leads us to conclude that appellant was not denied due process because those 

additional proceedings were not undertaken. 

The judgments of conviction are affirmed.

5 A trial court’s decision whether or not to undertake an informal inquiry is reviewed under the 

standard of abused discretion. Abushanab v. State, No. 10-16-00220-CR, 2017 Tex. App. LEXIS 5947, at

*2 (Tex. App.—Waco June 28, 2017, pet. ref’d) (mem. op., not designated for publication); Lawrence v. 

State, 169 S.W.3d 319, 322 (Tex. App.—Fort Worth 2005, pet. ref’d). And, discretion is abused when the 

decision falls outside the zone of reasonable disagreement. Devoe v. State, 354 S.W.3d 457 (Tex. Crim. 

App. 2011).
