Speeding

Police forces often have to divide their time between tackling street crime?

such as theft and assault, and chasing car drivers for offences such as speeding. When it comes to a straight
choice, street crime should always come first. It could be said, of course, that the consequences
of speeding can be far worse than the theft of a handbag or a mobile phone. But the important
difference between the two offences is that in one there is intention to harm the victim, or deprive
them of their property, whereas in the other any harm that is done, however serious, is usually
accidental. Therefore criminals who assault and steal from people are more of a threat to law
and order than those who commit traffic offences.
