It isn't practical to disarm the cops.
But their training should be different.
Those trained in military tactics & supplied with tools of that trade are a problem.
As they say, to a carpenter all problems look like nails.
I think it is. Most police officers never touch their sidearm anyway, and very, very few have actually fired their arms in the line of duty. And then we have idiots who discharges their firearms when they don't need to.
I agree - training is good. Not having the option to do something stupid when you have already demonstrated your stupidity - that seems like a good thing to me.
Besides, if you don't have that option available, training will be a bit more creative, and officers will need to depend more on tactic and personality rather than intimidation.
My point is simple: the insanity in Ferguson needs immediate action - not more hostility from the police to subdue citizens, but citizens disarming the police - at least forcing them to be less violent. Then we can remedy the situation. I don't see how we can progress if the police stand their ground with brutality and citizens being persecuted and killed for doing what they have the right to do.
