No one cares or thinks there are too many police...until they are coming for you or your family.
Haven't watched the video yet so can't comment on it but I've read the Col's original book. Being conditioned to kill is not a good thing...
Modern militaries (and now by extension, increasingly militarized police) being full-time forces, rather than citizens called up in times of need, is sliding down a slippery slope. When someone's whole career/life is wrapped up in such a profession, of course they will lean towards violence when in doubt.
Time to bring back militias and Andy Griffith style lawmen.
That's all good and well and I'm not trying diminish your perspective, but that's not going to happen. Once the old timey cultural genie is out of the bottle there's no putting it back in (atleast in our lifetime).
In my vast experience on American soil for which the better part of two decades I was an outlaw of sorts (non-violent of course) I've never personally seen the police misbehave, quite the contrary, I've only ever seen the police doing their job in a professional manner. Much less have I experienced any type of "police state." In fact, there have been several times in my life when I wished there were lots of head bashing authoritarian types of cops around to put some thugs in their place.
My hypothesis, which bears fruit from 50+ years of anecdotal experience on American soil, is that if you have a valid drivers license, a decent looking car that is insured, have no warrants out for your arrest, aren't out in public running your mouth and looking for trouble, and pay your taxes, that the police are your friends not your enemies. And you can never have too many friends. We need more police in America that are tougher on perps. This is also a thesis in the book Freakonomics... legal abortion (because mothers who are forced to have kids who don't want them raise deviant criminals), coupled with more police on the streets and 3 strikes tough sentencing laws reduce crime (as exemplified in the early 1990's American crime stats wherein 1970's single mother kids that wouldn't have been aborted at the onset of Roe v Wade in 1973 would have been coming of age and turning to crime).
I'm obviously anti-abortion, but if you want to reduce crime, allow women who don't want children easy access to abortion, flood the streets with tons of cops that bust heads, and enact tough 3 strikes sentencing laws that put recidivous felons in jail for life on their third felony. This approach seems to also be working well for Singapore which has one of the lowest crime rates on the planet.
