Yes you had a complaint, but look at your actions.
You stole keys. You threw them at kids. You made demands.
I think you should be careful YOU don't fall foul of the law mate. It could have also turned out much worse for you, had you tried to grab him. I'm not saying I detest fly-tipping but you flew off the handle.
I sometimes ride a push-bike and have decided to give it up because I think the situation has got worse, not better. I am referring to people who seem to think that those on two wheels have no rights and that anyone else can make up their own riles as they go along regardless of the safety, in order to force them off the road. It's just too dangerous. Other countries have far better rights but in this country unless they kill you they can get away with an awful lot and they're more scared about cameras than they are crushing bones.
