Re: Hostage situations...
It looks like the problem starts with drawing one's weapon. When your really really southern not-really-neighbours get to this point, they start by drawing their key, going to the boot of the car, unlocking the safe inside it, and then drawing their weapon. If it got that far. Otherwise they just pull back and call in the specialists. Most of the bollocks gets solved well before then.
Confrontations don't typically escalate to drawn weapons, because almost no-one - crims or police - goes into them with the expectation of having a gun drawn immediately.
