Armed Response Officers in the UK don't use shotguns - much too indiscriminate.... In most instances nowadays they use Tasars backed up with dogs.

Wait a minute here... Are you trying to tell me that if a robbery goes bad and an armed robber is holding a store owner hostage, UK police are going to send in guys with Tasers and dogs? Bullshit! They're going to use the same tactics and the same weaponry cops everywhere would use in a similar situation.

Look, the tactical techniques and materials used by US police were borrowed from the US military. The tactical techniques and materials used by the US military were borrowed from the British military. Our Special Forces learned everything they know from British commandos. And you're trying to tell me that the police in the country which invented commando tactics don't have the equivalent of US S.W.A.T. teams?

As for shotguns being too indiscriminate, that's BS too. They're only indiscriminate if they're used indiscriminately. The reason US cops use them in certain situations (and, no, they don't use them in all situations) is that shotgun pellets don't ricochet like bullets do. Using handguns or rifles in urban areas where there's a lot of concrete and asphalt is very dangerous. A bullet ricocheting off a brick wall or sidewalk can still kill an innocent bystander hundreds of feet away.
