Nice to see the police setting an example. Today at 2.20pm on Webber Street, corner of Blackfriars Road, SE1.

For those who don’t know, this is an Advance Stop Line, a ‘safe place’ for cyclists to wait at junctions. If it wasn’t filled with two tonnes of Plod, that is.

The license number of the van is LX54 JBE.

‘Quis custodiet ipsos custodes?’ roughly translates as ‘Who watches the watchmen?’
