Easy. Most of them around here wobble about in the gutter and generally ride like they've never seen a bike before. The day I can't outrun the average cycling copper is the day I hang up my wheels for good!
It would not be wise to try to get away from a policeman if he was trying to pull you over for something. I'm not well up on the law but I think that in itself is an offence. There are however a few police who visit and contribute to this and other cycling forums and from what I read they would not be easy to get away from anyway!!!!!!!!!
Sadly my police provided mount would not stand much of a chance in a 'chase'! I was given a good bollocking when I suggested paying for my own improvements as a committee (snore) has to approve any procured items.
There was a news report around here of a cycling copper heading off after a drunk driver a while ago, caught him when he'd just arrived home, and nicked him. Can't find the news article though. The copper had used to race competetively and could shift a bit even on a police mountain bike.
Walker - I guess you could but by the time you've lost sight of him the
patrol car would turn up.
One of the ideas of the cycling coppers was that they can go places a car can't. Bikes can get away from cars without any problems at all. At least as far as the traffic round here goes.
I wouldn't manage it, because I'd stay on the roads, unlike my local coppers who seem quite happy to rid eon the pavements. I haven't seen any RLJ yet but they'd probably catch me up there too if they did.
