More about the blind man and the sword incident.

I read a few more articles about the blind man in england who was tasered by local police. They believed or thought that his white cane was a sword. They had been alerted to a man wandering around with a sword. They saw him walking with his cane. They called and told him to stop. The thing about this is that if you call out, "Stop. Hey stop." I would not necessarily know you were talking to me. You would have to say my name if you knew it or actually tap my shoulder or be very close to me. So, he did not stop and therefore was tasered. Very odd situation. Some major disability awareness training needs to be done pergh?
