Digby has another story about people being tazered.
Like most of these stories the use of these weapons are totally unnecessary.
An old man, with a white cane, in other words someone who is blind is mistaken for someone with a samurai sword. How the hell can someone who is supposed to be an observant public servant think a blind mans white cane is a samurai sword?
That's not a mistake, that is a compete dereliction of duty.
