What if somthing happens? What to do? You could run away like a baby, then you would get shot in the back of the head, so you need to fight back!
Get a tasor that isn't deadly (USUALLY) then when it happens, (BAD happens) you can whip out you trusty tasor! ZZZINNNGGG, your safe and while they are down, you can call 911, they'll come and te guy goes to jail, it works, but you have to know how to use it! They usually have a red lil lazor light right under where the carlege comes out, and it will point at the target, then ZZZTTTT you got em!
