You make a compelling statement there; in this case, as you mentioned, it's quite possible the gentleman is suffering from PTSD and thus unable to put things into perspective. Not sure if it can be mandated, but perhaps some training for officers might be in order if they already haven't had it.
That being said, for those who don't suffer from any type of emotional issue(s), I will stand by my position. Comply and deal with it through the legal system if you think you've been wronged.
