Police tickets

sounds like they were being over zealous, but I'm not sure you'd see kids and grown ups proper speeding down the pavement by angel tube - it's a very high density pedestrian area and it would generally be quite difficult to cycle down the pavement there in rush hour

however, having worked there for six years I saw plenty of idiots try. you also get some absolutely idiotic RLJing at that junction (given how busy the crossing is). so generally it's at least the kind of area they should be policing.

I had a warning given to me in front of Angel tube station, 7pm rush hour.
As I'm approaching the pavement, instead of dismounting, I rode along the very edge for about 3/5 meters, just to avoid messing with the cyclists behind me.
3 coppers came to me like fucking wolves hunting... it was obvious I wasn't cycling on the pavement, I tried to explain I hadn't even pedaled after leaving the tarmac... still I got a warning. They were all smiles as in I don't give a shit, we're talking to you so we need your details and you'll a little souvenir.
At the end I never stopped insisting they were over-doing their job, not being really accurate, they just smiled.

I see kids and grown-ups doing it everyday, like proper speeding, and the poopoos do nothing. So yes, as said before, there has to be common sense for what should be considered offensive and perfectly responsible bike handling (according to circumstances).
