Glad you can now see why Americans don't want to give them up. Come to America. If you are robbed you can at least try to shoot back!! lol.
Seriously, though, glad you got away safe. Hopefully the 'trash' takes itself out soon.
even assuming you're Sean Penn or Diane Frankenstein and can actually get a CCW in my area, by the time you're being robbed at gunpoint by a brew it's much too late to use your own gun

CCW is only going to help if you've got the observation skills of a SF and never let your guard down, or carry 2 bags of groceries, or go out with your wife and kids etc
a BIG aggressive dog or 2 is much better and brews are generally terrified of big black dogs
