Most crooks are opportunists, and they will take the low risk highest return option always, and they are not going to stop and read any signs on the lawn or front door that you own guns. So someone gets into your stuff, they just want to take something of value they can pawn off for cash quickly to satisfy what ever has driven them to take such chances. Really and totally not worth either you or the perpetrator getting into a gun battle if you think with your head and not your ego or genitalia.
Most folks also should keep in mind that movie shyte is just movie shyte, no saying how things would go down if there was an armed confrontation. Most folks who have a firearm pointed at them will discover their bladder will not hold up to the initial confrontation. No saying how a person would react under such duress, but guaranteed the perpetrator will have either their aggressive game or their wound-up scared shyte attitude already on. Confrontation might not end up how folks perceive it in their minds eye one on one on the street, at home or even in a house invasion or folks ganging up on them, but guaranteed, counter-aggression will bring them to some sort of snapping point.
I own guns (so dont bother with the he is Canadian and anti gun) because I am a farmer and the prime reason is to dispatch animals humanely and efficiently. I do not go on the hunt, I have neighbours and friends who do that quite effectively and they are sharing so I do not need to feed my ego or justify 'feeding my family' or what ever else is a reason in some minds.
I was properly trained in the use or a side arm and a long rifle to the level where I am effective and efficient with the use of either firearm. It is a skill I maintain. But I am not obsessed with the tools neither am I braggy or driven by other reasons to show off these tools.
The trouble I think is more in people's heads than anything else. Some folks are not wired right and should not have legal access to firearms, and I feel the laws should be such that access should not be granted to them. I also think it would be a good idea to hold not just the buyer but the vendor accountable when a firearm ends up in the wrong hands. Anywhere that has legislation and regulation for the purchase or ownership of firearms (or types of arms) should also hold the administration overseeing those rules accountable for the tools getting into the wrong hands.
...just my opinions...
