He hasn't been found guilty. As far as I am aware he has not even been charged.
The boy that is being threatened in the most vile ways had to be hospitalised after being bitten by a Rhodesian ridgeback. He had to witness a man killing the dog with a kitchen knife in trying to rescue him and a woman who was also bitten trying to save the boy.
That is a dreadful event for any child to live through. If he is guilty of arson it doesn't excuse his behaviour but to be threatened by adults is too much.
Whatever happened to him, he SHOULD NOT have set fire to Manchester Dogs Home killing innocent and trapped animals. I don't regard him as a 'child'. I regard him as someone who knew exactly what he was doing and I hope they throw the book at him! I have no sympathy for him whatsoever, all my sympathy is for the dogs who perished.
