Used to be most cops were imposing and respected figures. In many of the deadly cop killings lately, seems the cops aren't tough, but act tough. They are so strapped down in SWAT gear they are unable to handle a guy in handcuffs, thug threatening them with a knife or a hammer standing on a porch. They just kill because that's what they are trained to do, not wait, or tackle and subdue.  Shooting a guy with a gun, but a knife? Why I are you a cop? Cops used to just go after the guy, wrestle him to the ground, maybe get a black-eye or worse a stab wound. But that was the accepted risk of life as a cop. Now they just shoot. 

There was that little skinny little college kid with a knife a few days ago surrounded by three cops. None of them had the guts or the training to simple go the kid and risk injury, probably minor. At my age, I think I could have taken the kid. No, they just shot him 8 times. That's what modern day cops do today if your black or by chance, white.
