I dont seem to get into a whole lot of trouble (maybe being 6'3 - 250 has something to do with that....) I had a guy try to mug me my Freshman year of College, but as soon as he saw me pull my blade it was over. If I am out I am always carrying my compact 1911 concealed on my hip ( I have a licence) my CRKT knife on my pocket, and a SureFire on the belt. I have never drawn my gun, but if the situation arises that I have to use it, you bet your ass I will.
There was a comment earlier about shooting to kill. YOU ALWAYS SHOOT TO KILL! If you arent prepared to take a life, you shouldnt be shooting the in the first place. Also, If you shoot someone, and leave them disabled, its possble that you could be sued! Also, if you shoot someone, OC someone, strike someone, whatever, be PREPARED TO BE ARRESTED! You WILL be arrested. Charges may or may not be filed, but you must be prepared for this. If you are planning on carrying ANY weapon, spend some money on a good lawyer, if you use your weapon, you will need the lawyer.
