Yhat's not what the BP agents said originally. They only said that after it came out that one of them capped off an entire magazine at the guy--which is something that they were supposed to report at the time, and did not.
So, which version is the true one? Why should I believe either story told by the agents? Both of them cannot be simultaneously true, therefore at least one of them is a lie.
What police dept. did you used to work for?
