2 things here.Grevensher said:The point is to kill them before the bomb goes off. A police officer with a handgun can only shoot a suspect up to 100 meters away reliably. Those officers with rifles can shoot them up to 300 meters away.
1. Most of these attacks happen out of the blue, unless something is leaked out to the police times before... In which, an ARU or the "Real police" as you call them would already be dispatched before hand. So, unless you've caught this guy with a bomb on him, which is highly situational and improbable... A guns not really going to improve matters.
2. I'm pretty sure that NYPD doesn't have officers actively patrolling the streets with rifles outside of ceremonial circumstances or unless informed on a situation like this currently happening.
Please understand that I'm not arguing with American police officers carrying guns, I think over on your side of the pond, its a reasonable thing to do. I just don't think the whole watching out for terrorist argument holds much ground.
I do urge you to understand that Briton is not America and having every officer carrying a firearm is really unnecessary and as said in my post on page 14... We have enough idiot cops out there who I wouldn't trust with a baton, never mind giving them firearms. Leave it to the pro's who are trained specifically to handle this kind of situation. If the worse comes to it, we always have these guys to back it up http://www.youtube.com/watch?v=_p4DmuGyehc
