http://news.bbc.co.uk/1/hi/wales/south_west/82 25778.stm A blind man who complained to police about cars parking on a pavement was arrested when he threatened to let down the vehicles' tyres.
Daniel Duckfield, from Narberth, Pembrokeshire, said he and his guide dog had to walk in the road when paths were blocked by illegally-parked cars.
He has complained about being cautioned and put in a cell after his arrest. My first reactions on reading the article were sympathy with Mr Duckfield (and curiosity as to how he would let the tyres down since he was blind and the valves are pretty small).
But of course this is vigilante action - and surely it can't be condoned.
Should the fact that he is blind / disabled come into play?
If this was a mother with a pram or a person in a wheelchair, as with Mr Duckfield then there would be a lot of sympathy - but if it was just a 'white able bodied male in his 30s' would you have the same sympathy?
Try reading the article again but put in 'unemployed 18 year old youth' instead of 'a blind man' and see if you have the same degree of sympathy.
