CONCURRING O PINION

JUSTICE BROBSON DECIDED: NOVEMBER 16, 2023

I join the majority opinion in full, as I agree with its analysis and application of

Confrontation Clause 1 jurisprudence to the “Shotspotter Investigative Lead Summary”

(Summary ) at issue in this appeal. This is not to say that I am entirely at ease with the

trial court’s decision to admit the Summary over defense counsel’s hearsay objection,

particularly in light of the testimony about human involvement “in the ShotSpotter

proc ess.” (Maj. Op. at 4.) 2 In addition, I am intrigued by amici curiae’ s other rule

- based

1 The Confrontation Clause of the Sixth Amendment to the United States Constitution provides: “In all criminal prosecutions, the accused shall enjoy the right . . . to be confronted with the witnesses against him.”

2 I do not believe the Court’s recent deci sion in Commonwealth v. Wallace

, 289 A.3d 894 (Pa. 2023), relating to GPS data, forecloses this argument as it applies to the Summary specifically.[ J

argument addressed to the reliability, or authenticity, 3 of this particular technology (Maj.

Op. at 12 n.15), especially in light of the following disclaimer included in the Summary:

[T]his summary should only be used for initial investigative purposes . . . . This summary has been generated solely for the purpose for which it is provided. Nothing herein shall to any exte nt substitute for the independent investigation of the shooting incident. The data and conclusions herein should be corroborated with other evidentiary sources such as recovered shell casings and witness statements.

( Appellant’s Br., Appendix D at 3.) No netheless, the majority disposes of the only

question before this Court

— i.e

., Appellant’s Confrontation Clause argument. And, as

noted above, I join the majority opinion in full.

This matter, however, like our recent disposition in Wallace , illustrates th e complex

constitutional and evidentiary concerns that reasonably attach to what Justice Wecht

refers to in h is Concurring Opinion in Wallace as the use of “computer

- generated

evidence” (in contrast to “computer

- stored evidence”) at trial. Wallace , 289 A. 3d

at 908

- 09 (Wecht, J., concurring) (emphasis in original)

. One thing is certain, as

technology advances, particularly in the field of artificial intelligence, these concerns will

continue to arise

, and judges and litigators

— civil and criminal

— will conti nue to wrestle

with them. Accordingly, this may be the right time for the Court’s Committee on Rules of

Evidence to examine these concerns and assess whether our current rules are adequate

on the subject.

Justice Dougherty joins this concurring opinion.
