The aggravated assault rate has tripled since the 60’s. The reason Mayberry-style PD’s are out of fashion is because violent perps are the rule rather than the exception. It used to be that most perps understood that they were the bad guys, and gave up when cornered. These days, perps think they are the good guys, and their vicious conduct reflects it. Only much-improved emergency room care has prevented the tripling in the rate of shootings, stabbings and so on from tripling the homicide rate. Rap isn’t the cause of it - it is the symptom of an underclass radicalized by Zinn, Chomsky and all of other lefties pushing - via the public education system - their vision of an unjust America that needs to be put out of its misery. These people, both the perps and their relatives and friends, are as socialized in American society as lions and leopards are in African society.
It's time to go back to the hue and cry model of policing, with police actually on foot, unarmed, and walking a beat.
