Here's a post from the guy that is kind of buried in that forum thread, I'll quote it here:
Just got a call from my lawyer. After reviewing the video there will be no charges filed against me.(My lawyer is a good friend of one of the ADA's so they went over it this morning and the ADA said it was a clear case of self defense/protection of a firearm and blew off the idea of charging me) The security guard and store both declined yesterday and I was asked if I wished to press battery charges against the guy and declined at my lawyers advice. ( After all I am not the one laying in the hospital right now with a broken nose, fractured jaw and torn meniscus) My lawyer wanted to close this ASAP and the evidence is pretty damning for the guard. I was told to NOT name the store or guard or witnesses. My lawyer will retain a copy of the video but (at least for now) it will NOT be allowed to be posted.
The civil side is a different story and that will be investigated.
What did I learn...:
Do ONLY what you have to and not one bit more
Be respectful and answer PERTINENT questions the officers ask
Have a GOOD lawyer who already knows you and your personality
Do NOT get mad or take the cops questions personally. I was still shaking and pissed off but I remembered what Legacy said about them NEEDING all the facts and versions to make a judgement call. They just wanted my version of the facts and me being calm gave me better credibility. I WAS dis-armed while questioned but because I remained calm and spoke clearly and calmly and the witnesses backed my version of events I was actually handed my still loaded weapon back and told to go home and chill out.
