Is it time to start calling out bad cyclists?

southwark bridge road / upper thames street junction is very funny today - the police were standing there trying to stop cyclists, but they all just got off, crossed as peds and carried on. They have now blocked one ped crossing and reopened the cycle crossing going up towards queen street. One motorbike policeman can't stop 20 cyclists every time the lights change...

I wondered why they would go to the trouble of creating what appears to be a very nice cordoned off bike lane, only to put barriers in the middle of Upper Thames St - then this morning sticking a concrete block in the middle of the bike lane entrance, giving just enough clearance both sides?
