I think that the discussion on criminal and civil liability was very eye-opening. A lot of people don't realize what they're getting into until they hear that.
Just for example, they told us that if you use a gun to defend yourself, prepare to be arrested, because now you have to defend yourself against criminal charges. Later on, you will face civil charges. So, be sure that you only use it in a life threatening situation.
I'm not afraid of the guy who wants many guns; I'm afraid of the guy who wants just one.
