if you lived in texas you wouldent have that problem. most folks have guns, and the homeowner has a law on their side called the castle doctrine. the criminals should be afraid out here. once they cross the threshold into someones home they have forfeited their rights. as a homeowner you dont know if they are there to steal your stuff or harm you. use of lethal force is at the descretion of the homeowner if they are in your home or garage.
your vehicle is an extention of your home as well. this is one reason we dont have many if any car jackings. canada rounded up your guns, now the criminals have free reign, everybodys fair game to em now. if you the homeowner shoots a home invader in canada you will probably do jail time for owning an illegal gun.
sorry for your losses, just letting you know the criminal element in texas knows what can happen to them if they break and enter a residence, or attempt to carjack somebody. this is one of the reasons the gun helps out civilization and keeps people honest. it works here as a reasonable deterrent because the criminals dont know who is armed or not.
