These two officers are under both FBI and a departmental investigation in connection with an arrest captured on a cell phone. I can’t tell you what led to the arrest or what kind of resistance they had to overcome before the short portion of this event you can see.
The suspect here is 24 year-old, William Cardenas, a known gang member who was being arrested in connection with possession of a stolen gun.
AP talked with the attorney that reps the arrestee and published this story.
An update! Chief William Bratton responds on the LAPD blog.
