One blind man's self-defence crusade
A blind man from Scotland has begun teaching a class of blind and visually impaired students how to protect themselves.
David Black's self-protection class features the mobility aid most of the students already carry - a white cane.
He shows them how to use the cane to fend off an attacker.
One of the moves involves using the cane to put an assailant into a headlock.
Black trained as a self-defence teacher after he was set upon by assailants who tried to throw him in a canal.
His self-protection course runs at the Forth Valley Sensory Centre - where Black has worked as the cook until now.
