Crime or offence? All crimes are offences, but not all offences are crimes. Surely anyone caught speeding or using a handheld phone whilst driving has committed a crime because they have broken UK law. We may well think that nobody got hurt when driving at 15mph over the limit or chatting on the phone, so it's not a crime. But the law was broken, and you were caught, so it's a crime. Demoting the action to being called an offence minimises the perceived possible consequences and thus less effort is made to not take the action.
Whatever it's called though, education must be good. But not necessarily as a replacement for punishment.
