Anytime, a police shooting occurs. They quickly to response before investigation has started. The cover up starts the moment the bullets left the gun.
To serve and protect, now becomes to lie and fabricate. Cause within the mixture will be some fiction and a few facts. We accept mistakes happen.
It's like the job of a public defender. Conviction is most likely to happen to the one the defending. The cover up starts when the spokesperson speaks..
They most basing facts upon the explanation of the officer involved. And don't matter who's the witness? Like five standing there. They all going to describe a different version.
It's like the writers of the Gospel concerning Jesus.
