As an American, and therefore born gun-lover, if stereotypes are to be believed, I vote no. See, in the US of A, police need guns because criminals have easy access to guns, and the police being unarmed would leave them at a disadvantage. Over in the UK, the criminals are not armed, so why the hell do the police need guns? So they can not shoot anybody, since they are pretty much never going to have the right to use lethal force? After all, most cases in the US of lethal force being authorized are the police either having a suspect aim at them with a gun, or appear to be reaching for a gun. Take away the gun, and you have an unauthorized shooting.
Tasers, on the other hand, make sense. If you've got a suspect charging you with a knife, you want to have some way to subdue him quickly. But a gun is not necessary, given UK gun laws.
