BART Police Officer in Oakland Filmed While Killing Helpless Man

Subway riders in Oakland, California shot videos on their cellphone cameras of a group of police officers handcuffing several young men on a subway platform. A couple of the officers throw a man face-first onto the ground, sit on him with their knees and then one shoots him to death.

There's lots of video of this horrific killing.

Here's one angle on the homicide. The killing happens at the 1 minute 15 second point in the video. Watch the officer in the back pull his gun, aim it and fire it into the man's back.



Here's another angle from which you can clearly see the officer drawing his weapon and aiming it down at the victim:



This alleged police officer shoots a totally helpless man in front of dozens of onlookers while being filmed!

The alleged officer's name has been released. He is apparently Johannes Mehserle of the BART Police Department in Oakland, California. So, there are news reports that this man is being moved from place to place in order to protect him from harm because he has received death threats.

People with cameras filmed this police action starting well before the seeming execution. Why would they do that? Possibly because they knew there was something suspect in the police activity. Watch the video of the moments just after the killing. Look at the other police officers. They're just standing there. A man has been shot in the back and these other jackasses are standing around as if someone's received a parking ticket. Do these officers have Nazi regalia in their homes? Are they skinheads? Are they Ku Klux Klan?

Cities burn for stuff like this. Rodney King. Remember? The cops only beat that guy with sticks and Los Angeles went up in riots and flames. This man was shot to death in public in Oakland. Looks like murder.

Protests are forming.

BART officials have made statements urging calm until the facts are known. BART can put the facts up its ass. The facts are on video.

Questions:

Why wasn't the killing officer arrested immediately on suspicion of murder?
Why do the other cops stand around looking bored after the killing?
Why are the bystanders already filming from so many angles well before the killing?
