Actually this is no joking matter. Someone reported seeing a man with a samurai sword and police with tasers were dispatched. The policeman who tasered – and tightly handcuffed – the blind man mistook his white stick for a sword. A katana, the sword usually described as a samurai sword, is a big curved weapon. You have to be quite close to a person to use a taser effectively – certainly close enough to distinguish between a blind man's stick and a large Japanese sword. Clearly, the policeman wasn't following the guidelines and that is very worrying. This is not the first instance of police using tasers inappropriately.
