Is it time to start calling out bad cyclists?

I have seen the police signal to cyclists to dismount while on the pavement. The law is certainly there for a reason, if someone is a complete and utter cunt and thinks its OK to do 20+ mph on the pavement, they will then have the power to take action. I really can not stand people who can not differentiate between situations. cliveo gives me the impression he would lock up a 7 year old for cycling on the pavement.

Didn't Clive make it clear in his first post that the man was in his 20s?

Also the speed needn't be 20mph+ to for it to be anti-social, a collision even at walking speed would be unpleasant. Especially to and elderly or infirm people who may be using the pavement. It is not solely for the cyclist to determine if their actions are dangerous, you have to take into account other peoples perceptions of danger and the distress it may cause them.

From Clive's description this guy had no need to be cycling on the pavement and calling him out for it was the right thing to do.
