Any tips on effectuating #2?
If something bad is going down, use your cell to dial 911, and start feeding intel to dispatch in real time as you move to act. You should be sure to ID yourself and give your physical description so hopefully it gets passed on to the responding officers. If the bad guy(s) whack you, at least the inital responder have some idea what's going on.
Don't be visibly armed when responding officers get there. Meaning reholster, if possible.
If you are confronted by officers, comply. This is not the time to debate while being taken down at gunpoint. Drop your gun. I don't care if it's a $5,000 Nighthawk Custom. You can buy a new gun, you can't buy a new head.
