Sitting on the fence?

What do you think of this decision by the Home Secretary to arm more police officers with Taser stun guns? I see it in two ways. If it means that there will be less use by the Police of fire-arms, with a consequent saving of life, then that must be a good thing. My concern however is that, knowing they have (at least theoretically) a non-lethal weapon, officers will be more likely to use it. That certainly appears to be the situation over in the States, and as we know, what happens over there usually ends up happening over here. So on balance, I approve, but with reservations.
