City officials in Williams Lake, B.C., want to the change the way the courts handle prolific offenders.

The central Interior city has been dealing with a high crime rate for a number of years.

RCMP detachment commander Insp. Warren Brown says the vast majority of their crime is committed by prolific offenders.

"When those folks commit 30, 40, 50, upwards 100 offences over a number of years, it's worth our while to make efforts to target and try assist those individuals."

But Williams Lake Coun. Sue Zacharias says judges aren't allowed to consider past convictions when making a judgement on a single charge.

"We're letting society down by not having the judges being able to consider the record of these repeat prolific offenders,” she said.

"It's costing the tax payers a lot of money. The cost to society is huge."

Williams Lake has put forward a resolution at the Union of B.C. Municipalities (UBCM) convention underway in Vancouver.

It calls for the UBCM to ask Ottawa and the province to allow past crimes to be considered during prosecution.
