Uhh......Where does the Taurus live? Seems like it might beat knives and bits of wood.
In Oz he MUST keep all fire arms locked up at all times and he's subject to random inspection .
The odds are probably fairly low, but if he got caught he would lose everything .
And if he did shoot an intruder the first thing they would look into would be how he got to a gun fast enough for it to do any good.
