SIR - It appears police in London are given permission to knock motorbike/scooter riders off of their bikes if they have been involved in crime. These miscreants use bikes to commit crimes or joy ride. They believe they can get away with doing it because police giving chase can’t stop them, especially if they are not wearing a crash helmet.

Too often we hear that police had to back off because they risked the rider falling off their bike. That would be tough justice but so what. These people don’t give a damn that they put others at risk.

The sooner permission is given and rolled out across the whole of the UK, the quicker bike/scooter crime will, hopefully, disappear.
