Hey, there are pros and there are CS cops. I was disappointed to see the Va. State Police cowering behind their cars at Va Tech that morning with all their killing gear while one psycho wandered the halls killing people with a handgun. I've been disappointed in the past to see a cop grab one guy on a motorcycle out of a pack of cars doing 75/65 because it's an easy bust. By and large, cops aren't cops anymore, they're civil servants waiting for their pension. Or a move up to federal service. Along the way they want it easy. And safe.
Face it, many big-city and country P.D.'s demand a degree now, which of course, after a few years on the street enables them to move to Federal service (the Feebs, DEA, Treasury, whatever) which takes them further from the street and into the ether. Drones, warrantless searches, taps, domestic surveillance, it's all on the table for enactment. People must be ok with it, I hear hardly a peep of dissent from anyone that matters. And those are the big issues.
Instead, the media takes the easy route and endlessly plays the tapes from cops giving a mutt that ran from a simple traffic stop the roughing up he deserves when they finally catch him. They take issue with a cop shooting someone that clearly had it coming. But the Constitutional issues, except from the Op/Ed pundits, never get air time, and frankly, I don't know that the folks at the grass roots care. But that's how it creeps up, incrementally and slowly. Before you know it, you're fresh out of the old protections and there's no rolling back.
