"THE police have been instructed to let off offenders with a caution if they commit any one of more than 60 types of crime, ranging from assault to some types of theft, criminal damage and under-aged sex. The instructions are contained in a government document sent to forces and released under the Freedom of Information Act. They are designed to reduce inconsistencies that can see offenders in one area escaping with a caution while elsewhere they would be prosecuted for the same offence."
