A) Currently at this time? No. Not allowed to bring my rifle to college.Zhukov said:Can you please define your question a bit more clearly?
I can't tell exactly what you're asking. When you say "can you", do you mean...
a) Do I personally have the ability to use a gun in self defence? (Kinda. I have some training, but I haven't handled a gun for years. I'd need a refresher.)
b) Is a gun a viable self defence weapon? (Yes, obviously. Although not quite to the degree that a lot of people think.)
c) Are you legally in the right if you defend yourself with a gun? (No idea. It would vary between countries and states anyway.)
B) Completely. Defense is not simply the art of deflecting blows, but also of counter attacks and rendering the enemy unable to commit offensive actions against you. Making them unable or unwilling by either killing them or making them back down. I have read studies that said that around 90% of defensive gun usages do not even involve the gun being fired, but I haven't been able to find it.
C) Here it is, although I live in California, so it isn't "as legal" as it is in other states. Some states are "Stand Your Ground" where you cannot be persecuted if you shoot somebody on your property without provoking them to come onto your property, while California is a "Duty to Retreat" state where you must try to get away from danger before your "allowed" to use lethal force. What constitutes "sufficient attempts to flee" is left extremely vague and can allow a person to be persecuted if the police feels like it. You cannot carry a gun on you unless you get a "Conceal Carry License". Unlike most states, which are "Shall Issue" (if you ask for one, the police are mandated to give you one unless you don't pass the background check), California is "Shall Issue," which leaves it up to the individual county sherifs if they feel like giving a person a CCW, and the most of the time, unless you live in the central valley, are personal friends with the sherif, or give many "donations" to the police department, 99 times out of 100 they are going to reject your request.
