Because taze first and ask questions/apologize later seems to be the protocol these days, police in England tazed 61-year old blind man Colin Farmer after mistaking his white cane for a samurai sword. To be fair though, police were on the lookout for a man who actually WAS running around the town drunk with a samurai sword, this just wasn't him. This was a 61-year old blind guy. No word how many cell phones they've mistaken for handguns.
