Does that relieve the officer of his responsibility in this. Probably not...however the guy was having difficulty standing, sitting and walking without assistance from the get go.
I think we're going to find he was likely intoxicated/drugged , belligerent and incoherent. As for the officer's conduct....that remains a question if or not he went too far in securing the guy. But he certainly wasn't there to deliberately murder anyone.
Agree with you completely. This rush to judgment has to stop and lumping this guy in with the Brown’s of the world is too much.
