Yes, you should! But what state do you live in? Is it easy to get a CCW permit/license? Always remember, if you shoot someone, you may NOT be convicted criminally, but the family of your victim could sue you in civil court. If you take the CCW class, they should cover most of the laws there for you. They also should be able to answer any questions you might have. Good luck True Conservative, I'm so sorry you have a business in a bad area.
