A guy wakes up to find his house being firebombed by three masked intruders. He pulls his Smith & Wesson from the safe, loads a few bullets, and fires off a few warning rounds.
For this, he is arrested by the police and faces jail time.
Look, I'm just as in favour of protecting the rights of mask-wearing, property-intruding firebombers as the next right-thinking leftist-drenched Canadian, but, call me crazy, a guy who firebombs your house wearing a mask and suddenly finds he has a hole or two in his body has nothing to complain about.
Careless use of a firearm? The only possible grounds are that he missed.
And that's the way the Ball bounces.
