I express this all the time with my wife and at Shows like "First 48hrs".First, it's a shame we have to defend ourselves in a good shoot.
Second, NEVER, NEVER, NEVER talk to the police or anyone without an attorney. He "asked for an attorney but continued talking voluntarily."? Stupid, stupid, stupid!
Third, racial slurs? Bullshit. Total misdirection. Play the race card.
Most important point is the second. Articulate you will not answer questions and you are exercising your 5th amendment rights. Talk to your attorney first! I cannot say this strongly enough.
Not just self defense. The law seems to want to hold leverage over citizens even when they aren't directly involved. Tons of examples.
