Police spotting (junction watch)

Saw a fella try and bomb away from the first lot - only to get stopped by some of their colleagues down the road - As I rode past he was getting handcuffed.

Always wondered what would happen if you didn't stop.

Tried it once after being shouted at by a PO on foot, only to be chased by another cyclist who wanted to tell me that the PO was talking to me.
Ahole.
