yay for unnecessary vigilantism.
Yes, this is the reason for concealed carry, to allow for citizens to stand up for other citizens. But there are times when it is appropriate, and times when standing by is the more appropriate action. It can be a tough call, and that is why everyone needs thorough development on proper decision making. Carrying a weapon doesn't automatically grant you the right to shoot, without question, every time a crime may be witnessed.
Note: I'm completely in favor of concealed carry, and in favor of appropriate justice.
No, but my line is when my life is in danger. A guy with a gun in a store I'm in waving it around threatening people = my life in danger.
Browns chicken anyone? You never know if the guy is going to start shooting. It's best to take him down as soon as it is reasonably safe to do so. Now if I see a guy running from a walmart and a employee yelling stop, thief. I'm not going to put a few holes into him. In fact I'll probably just keep on walking.
Everyone has their own threshold. For me it's when I think my life is in immediate danger. If you are 'robbing' the store I'm in waving a gun around, I'm going to conciser that immediate danger. If I think I have a chance to get a shot off I'm going for it.
Honestly, I don't carry a gun to protect those around me. I carry to protect myself and my family. Luckily for me, I live in a state that lets me protect myself first and foremost. If a man had a gun and was threatening people with it, I don't see a reason you should just stand by a wait to see what happens.
