Listen to Mr. Xrow :3.
1. Let him throw the first punch. That way if you hurt/kill him, you get in less trouble.
2. IF you kill him NEAR your house, DRAG HIM INTO YOUR HOUSE. That way you won't get busted, because technically you would have been "Defending your family."
3. Bring friends and tell them only to fight if the rest of the beaners hop in.
4. MOST IMPORTANTLY Keep the immigration department on speed dial and before the fight, threaten to send em back to Mehico if anyone but that ratard jumps in. If they're stupid enough they'll believe you :3.
