Technically innocent until guilty, in reality some chode, running away from the coppers, on a moped that was stolen 30 mins earlier violently, is obviously guilty.
There is no need to pamper criminals. As much action should be taken as possible to prevent them from repeating their mistakes. I'm all for forgiving once or twice, but now you have thieves and pickpockets who are being caught for the 10th time or so, laugh it off with a couple of weeks in the can, and continue to plague the working man like before when they're free. These people do not need protection, if anything they should receive help so that Darwinism does its job ( and they ride into a tree or post without their helmet, at least that stops them from being thieving scum for a while or for ever).
