Yours is a difficult comment to respond to.  You make assumptions and then extend your comment on the basis of the assumptions that you make.  Essentially, this comprises talking to yourself.  

Blame is a relatively juvenile concept.  Discussion of efficacy of method as an attempt to optimize future results provides benefit.  If method employed is observed to lead to unfortunate results, it is profitable to examine that method and determine whether changes could reduce or eliminate unfortunate results observed.  The LE tactic of immediate confront and control is very widespread and precludes calm and careful evaluation of unknown situations which you point out they routinely encounter.  Rather than breaking a door down and surprising a "perp" who then reacts without thinking, a more restrained engagement technique could be employed.

Careful consideration of methods is important and it is not arrogant to question efficacy of the status quo. 

Thank you for your comment.
