If LE accreditation agencies, police acadamies, and training seminars drew a line in the sand for zero tolerance of 4th and 5th Amendment violations, there would be a huge change practically overnight.
Who came up with idea of sending SWAT teams for even minor warrants? Who spread the idea?
Who came up with idea of automatically shooting all dogs during searches? Who spread the idea?
Who plants the idea that any gun is dangerous? Or, a woodcarver's knife when he is not even facing you? But, then does not teach the other side of the coin for judgement?
Who teaches the domination doctrine? The "take control" doctrine?
This stuff all goes hand-in-hand.
Somebody or somebodies is cleverly figuring out this stuff for the next police policy. Its not like 45 different departments all across the county suddenly all have the same original idea.
My money is on the acceditation agencies, trainers, consultants for disseminating the info. And, maybe even coming up with some of it.
Too bad they don't also seem to be teaching judgement, and demanding respect for 4A and 5A rights. They keep up the trend and soon the backlash may be nearly as bad as that against Writs of Assistance. The colonists were bent because of the searches done under the Writs. But, if you read up on it, you find they were also rather bent because of the way the heartless, self-interested thugs executed the searches.
