I'm not sure the police mishandled the situation. The first thing they have to do is determine what happened. Pray that you never have to shoot someone, because the police and prosecutor will assume that you are guilty until you prove otherwise.
I don't think that he should have been thrown in jail for 35 hours. I think that they should have made a better effort at the scene to find out what happened.
Watch as much of this as you can stomach. It occurred a couple of years ago. The police totally mishandled the situation. It's events like this which give people pause about policemen in general. It's the reason why people are so mad at the police all over the country. It's the reason why Black Lives Matter, SJWs, and mainstream media can inflame and enrage a nation. It's the reason why gun sales are through the roof. It's the reason why George Floyd and so many others are dead. Just imagine, if 7 out of 10 Americans ages 18 -24 can't meet the requirements necessary to enter the military, who are the police departments hiring?
