Saw a bike locked to a lamp post with one of those 'U' / 'D' shaped locks.
Pasty faced thin man walks up, lifts lock up over saddle, gets on bike and rides away leaving lock in situ.
Have I just see a bike being nicked?
Other than making 'firm' eye contact, I did nothing. No time to take picture with phone before there was but a red sweatshirt cycling away in the distance.
What should I have done?
