Are We The People purposely ordered to be targeted as future exercises? Are incidents created out of trivial matters a matter of spreading the word that random Brownshirt intimidation and abuse of civil rights WILL be conducted often -- with impunity? Is the citizenry purposely being conditioned and/or baited?
Nope. As Mr. Balko put it, "Partisan reaction to aggressive police actions against opponents tends to fall somewhere between indifference and schadenfreude."
