I don't even want to comment into this thread, but I will say one small thing, with many words. Time is of the essence, positively identify the bad bastards, drop as many as you can, and raise your damn hands when LE arrives. You'll know when they're almost there, so get that schit unloaded and the round out of the chamber (locked back), and drop that thing on the floor when they come in.
If you're in danger, act quickly. Be positive, but act quickly. You have the rest of your life to figure that out...
