A man is arrested for organising a water fight!
So maybe there is slight possibility he was using 'water fight' to mean riot as the plod suggest, did they ask him I wonder? Maybe it wasn't a very bright idea to try and organise an outdoor event near a riot zone, I can empathise with that. But I'm more inclined to think that Essex plod simply decided that anyone who organises anything over Blackberry messenger is a rioter.
I'm not happy about the system we now have but (at least for the moment) it is what it is, and it's the only system of behavior control we are allowed, hence we need the police to tackle crime, and I'm content for them to be as hard as they like on the real criminals who destroy property, security and our communities. But you certainly don't have to look very far to understand why the average member of the population holds the police in such low regard when they continue to apply laws and powers designed to fight serious crime to ordinary people.
"no tolerance" if applied as a process should be applied to all wrongdoers, which includes expenses fiddling MPs and (now) civil servants abusing taxpayer funded credit cards, and the police need powers to enable that. But if the police expect any level of co-operation and respect from the public they must learn to stop applying such powers against people doing ordinary and harmless, and even entertaining things. I realise almost anything can be an offensive weapon but a water pistol? What is the crime, aggravated watering of the grass with intent?
