When my husband took a gun safety test (that I plan to take this summer), on of the first thing that the instructor did was show them a single bullet.

He then went on to say "this is a million dollar bullet. Because if you shoot and kill someone, their family will sue you. They will take away everything from you. All your possesions, everything you've worked for. So before you pull that trigger, you have to ask yourself, is it worth it? "
