You should treat cops like people who might shoot you without a good reason. You shouldn't look at them, you shouldn't talk to them
No, no and no. That minding only exist in America and it's honestly very dangerous. People shouldn't fear policemen (unless they have some reason to). No wonder violence is so high compared to the Western World. People will solve their issues with their own guns between each other instead of calling police.
Police should protect. Right now, police is making people afraid.
Part of how the police protect people is by making people afraid of them. Of course, you can call the police and they might decide to help you if they choose to. But, if you don't have any business with police, it's best to keep clear of them and let them do their job.
This whole story is just a human tragedy brought on by our gun obsession. Guns carry a tax in people's lives and bodies. Most people don't really care because most of the victims are poor and black or latino. But, as long as we have crime infested, gun infested cities, we'll regularly have these accidents. Some people want to put all the blame on individual cops or on racism, which is always a factor. But, the real problem is that we care more about protecting a hobby than protecting black kids.
