Droc you realize that they are peace officers right? Besides the natural right that every human has to defend themselves, they work in an environment that is dangerous, and have that reason to be armed too.
Seriously, it doesn't strike you as odd that the border guards are defenceless? Not a tiny bit? Unarmed border guards? To me it's too unbelievably stupid.
The only reason they aren't armed is because it's Liberal 'policy', but not law. They're human beings, they're in danger, they're peace officers. 3 reasons they should be armed.
