Interesting question and one that has a lot of research behind it.

1. You're absolutely right. Department culture plays a huge role in unarmed police shootings. When cops are trained to de-escalate, they tend to do just that.
2. Multiethnic police forces, patrol teams and units. It's harder to make generalizations about other races when you trust your life to someone of a different ethnic make up daily.
3. Change the police culture of better tried by 12 than carried by six. Yes, cops are actually taught this.
4. Stop militarizing police! If they need this much firepower, we definitely need to change gun laws!
5. Accountability. Change the laws that allow cops to murder out of fear for their lives, rather than imperical evidence. I'm afraid of kittens, it doesn't mean I get to shoot to kill. Make cops criminally responsible for errors in judgement. (I'll leave obvious abuses like planting drugs and guns alone).
6. Prosecute bad cops!! Protecting the bad apples only lowers public trust, encourages corruption and fosters an us v. them mentality.

Since none of this will happen, yes, I agree international sanctions are in order.

It sounds too simple or easy to suggest education education education but then again education isn't simple or ever completed.

I think the US should look to the countries that have the least amount of violence and then emulate them. There are many countries that are far less violent.

It will take 2 things: (1) leadership from the top which lets all officers know that such behavior will not be tolerated. and enforces the demand --without exception, (2) a judicial system willing and able to press charges and get convictions.

The police are not being trained to kill civilians. What is happening is that the wrong people are getting hired as police officers. It is only a few members of that group that keeps doing the same bad things. They mistreat people, the think that the badge give them the right to do anything. I know several people that had bad experiences with police officers. I know a few bad police officers that should never have been hired. I am an black man and an ex cop. I have seen and heard things that should never been said and done. Believe me it is a small majority of police officers. There are more bad ones in the southern states.

Intense psychological testing of applicants.
Number one question should be "why do you want to be a police officer?"
With so many instances of cops killing unarmed (mostly black) people and getting exonerated, there is corruption in the system.
Weed out the dirty cops and judges.

I discussed the issue of unethical police with Dr. Anthony Pinn, Professor at Rice University in Texas. He stated that abusive police is a symptom of the injustices in our country. If and when USA becomes a more fair and just place to live, the situation will get better. Fighting racism, improving the status of women, ending poverty - when enough people tackle these formidable problems, the instances of abuse will improve. At the same time, citizens must keep on pressuring police departments when abusive behavior is brought to light. There are former cops and retired cops who have written about this too - I am currently reading a book by Norm Stamper, former Police Chief of Seattle. Improved training is necessary, very necessary.

Everybody has cell phones nowadays. Step up, record, step forward! Yes it is scary, they may turn on you, but there is power in numbers. We must stand together or go down one by one.

A few things would really help, in my opinion.

Require cops to live in the communities they police.
Hold community events in which officers interact with their communities in positive ways.
Bring back well-marked police cars and encourage police to greet people and make themselves available to help those in need.
Non-police oversight in departments.
Hiring standards that encourage diversity and thoughtfulness, rather than getting the aggressive and cold.

Sure, it will take some time to get there, but we can reduce police violence if we remove the occupying force mentality. And I think these would be helpful steps toward that.

Have you read 1984 ?????

We need the UN to step in. The militarization of our local police has gone way too far. They view anybody that questions them as an enemy and fair game to murder. I am very fearful of even being pulled for a traffic violation because of this attitude and I’m an old geezer of 64! I won’t roll over. They are supposed to serve and protect, not shoot and torture. I know it is a rough job, but they must be reigned in.

This is a scary time we live in when it comes to police brutality. I don't know how we should deal with it, but I do know that sometimes I get so angry that I wonder if maybe it isn't time to do away with the Justice system as it is now, and find another way to deal with our policing system. We have a problem, and it's as bad as Russia and China. In fact, it may be worse.

Public oversight; constant vigilance... rotating folks out from one job. Really, no lifetime civil servants... All citizens doing a stint in some arena of public service; including some folks in police enforcement.

Honestly, I have no idea. There isn't just a simple solution for this question because the cause ranges from bigotry to out right murderous intent.

Become a policeman

The December issue of the "Smithsonian" is about America's greatest new ideas. One of the visionary's is Ava Duvernay who directed the video 13th which is now on Netflix (and I just finished watching it).

If you watch it watch it alone because you might beat up the person next to you! It is a kick in the gut.

Walmart is the biggest gun dealer in the country and the world's biggest seller of bullets.

I would suggest taking a citizens academy if your area departments have them, a lot can be learned from the course and they are relatively short. one thing that would most likely help would be shorter shifts. instead of 2 12 hour shifts have 3 8's rotating through out. Mandatory counseling there is a stigma within law enforcment that we will be fired or looked down on for attempting to get mental help. I've been working corrections for over 11yrs and bounced a bar for 2 before that. I live with a term now called professional paranoia. more than likely stemming from PTSD due to what I've seen inside the walls as well as prior incidents from bouncing, and yes i'm one of the few that do get counseling. as a side note I opened up this thread and found exactly what I thought I would see.
Suicide Rates for 2016:
General public 13/100,000
Police: 12/100,000
Army 20/100,000

Until the police start to police themselves, and honest judges start handling cases, I'm afraid not much. Our government no longer listens to the people, so until they are replaced or what ever it takes. Not much will change.

Bailiff. Wack their pee pees!

OH MY... most of these comments are completely ridiculous and stupid. according to many LIBERAL Professors form EIVY league schools there is ZERO evidence of racial bias among police, there are actual reports from both the FBI and OBAMA administration that suggest police are MORE likely to shoot a white suspect that a black. There is countless studies by LIBERAL university's that say there is NO evidence to suggest American police force is excessively violent or racist. Apart from the few exceptions which are prosecuted and punished by law, the vast majority of cases are found to be justified by a jury or peers (everyday civilians) who looked at body cam footage and evidence and found the officer to be doing his JOB in the best of his ability and within the complete boundary's of reason. The American judicial system is not perfect, However, It is by FAR more just and fair than most of the worlds. so suggesting that we are evil. I suggest you move to a country without our laws and protection.

I hate to ask the stupid question but... What are we doing about Criminal Brutality?

Something has to be done through Congress-perhaps after the bloodbath election of 2018 and tRUMPs impeachment Congress will come to their senses and pass some law against police brutality and fund sensitivity training.

"Innocent until proven guilty" no longer exists. Attract the attention of the police, by, say, breathing, clearly you deserve a beating...if you are lucky.
I never gave a thought to my race, age...now I am Incredibly grateful to be an old white woman, and it makes me want to vomit that this is so.

take on the judges who side with the calvinists and bigots. appoint them instead of voting for them . that might remove the money from the process. jails are big business. the states have 32 million people who are or have been in jail and 4 million of those are in for 30 years or more. A higher rate of incarceration than Stalin's soviet union !
