Rioting is dumb. But......
We are at a point now where I honestly don't know if police - civilian will ever return to normal. The slew of cop killings lately has been ridiculous. The choking in NYC last year, the accidental shooting of the man in OK by the rent-a-cop, the Charleston shooting. It all looks real bad on cops. And let's face it, cops don't need help looking like power-hungry, mean, uncaring assholes. I'm white and my personal experiences with cops are overwhelmingly very negative, and one never even been arrested.
Look I know there are a lot of good cops out there, but we need to have a serious, nationwide discussion about police, police training, and appropriate police tactics. I, for one, believe it's ridiculous that police are trained to shoot to kill, regardless of scenario. I also think tasers shouldn't be part of a policeman's arsenal. But that's just my opinion. Either way, something needs to be done to ease tension between police and the citizenry they're supposed to protect.
All that being said though, that's zero excuse for rioting, and everyone who participates should be punished to the fullest extent of the law, as well as held financially liable for all damages.
