Whatever. When cops become too fearful to use force and very bad people get away to commit additional crimes, don't whine to them about it.
It all comes down to common sense. It's all about right and wrong. It's all about justice, equal punishment for crimes, and holding everyone to the same moral standards. It's about the value of human life, being civilized instead of being barbaric and inhumane, and about responsibility for our actions.
I watched the video several times, and never saw the young man go towards the officers. He spun around in place, and was immediately gunned down like an animal. The shooter should get life in prison without the possibility of parole. We can NOT allow cops to act as judge, jury, and prosecutor on our streets. The officer could have just as easily maced him, stunned him, or shot him in the legs. Deadly force was not necessary, as the video clearly shows. Also, he was shot something like 13 times, many of those shots occurred while the young man was already on the ground dying.
You can defend the sorry low-life pieces of shit all you want, but it doesn't change the facts. You'd be singing a much different tune if the young man had been your son, brother, or a loved one. The video doesn't lie. The young man was NOT an immediate threat to the officer. He was a trigger happy mental retard to take a human life in the manner in which it occurred.
