I am very tired of the way law enforcement is being treated on a lot of fronts. The majority are good people with a horribly thankless job.
Yes, the media fueled cases such as Ferguson and the like drive me nuts. Constantly wanting to make something a race issue just to get ratings is beyond annoying.
Now with those things said, is there a problem with some people and methods practiced in law enforcement? Absolutely. As mentioned, there are a few bad seeds. That is the case in any line of work. But IMHO, one problem is the lack of appropriate punishment dealt to some of those bad seeds. It leaves a bad taste in the public's mouth to see someone get a lesser sentence for a crime (if they get one at all) just because they have a badge. And let's be honest. This has happened. Much more than it ever should have.
Add into the equation these ridiculous "no knock" warrants where the wrong address is stormed, the situations where a cop overreacts and shoots a guy for reaching into his car to get his paperwork after being instructed to by the officer, family pets being shot and killed, etc., and there begins to be a pissed off public. And rightfully so. Clearly some changes need to be made. Anything from being more careful to make sure you get an address correct before going into a house with guns blazing to better screening of applicants and better training of officers to make sure they are capable of keeping a cool head in a situation. Also, implimenting better tactics of defusing a situation as opposed to d-ck measuring contests from the arrogant "Respect my authorityyy!" bully a-hole that just makes a situation worse. Everybody here has probably dealt with this type. He's the one that stereotypical "bad cops" are based on in many cases.
All of that text to say, in some cases, useful, respectful protesting or other chosen forms of publicly letting the powers that be know changes need to be made, I am ok with. The "hands up, don't shoot" BS protests and the like... Not so much. And sadly, those get the media coverage the most.
