Car thieves have new enemy
Police camera scans 200 plates per minute

CITY police unveiled a high-tech camera Thursday that scans the licence plates of hundreds of vehicles zooming by in a one-minute span to help identify stolen vehicles.
And investigators say the system, when installed, could help stem Winnipeg's auto-theft epidemic and reduce dangerous high-speed police chases.
The new camera system is called Automatic Licence Plate Recognition and it scours roads and parking lots looking for stolen vehicles.
Police say it's just one tool of many needed to make streets safer.
"It's not going to be a tool that cures everything," said Staff Sgt. Aubrey Kehler, of the stolen auto unit.
The system can read and compare the plates of 200 vehicles per minute. Normally, it takes an officer two minutes to type in a plate number in an on-board computer of a police car and get a reply, said Sgt. Doug Safioles.
ALPR facts
Automatic Licence Plate Recognition (ALPR) is a camera-based system used to identify vehicles by their licence plates.
The cameras can be stationary, used at a gas station, parking lot or border crossing, or installed in a marked or unmarked police car.
The ALPR automatically reads a licence plate and within seconds checks it with stolen-vehicle lists. It can also check if the car is legally registered and insured, but police don't plan to use it for that in Winnipeg.
The technology is used by police and border-security agencies throughout the world. RCMP in British Columbia will start using the system this fall.
Police usually store the licence plate information for 30 days. If there are no "hits" the information is destroyed.
Police say the ALPR system is not an invasion of privacy, as vehicle licence plates are in the public domain.
Police also say the ALPR system only does what police officers do already, but in seconds and more efficiently.
Recent stolen vehicles
March 17
23 vehicles were reported stolen. There were another 11 reported attempted thefts.
March 21
11 vehicles were reported stolen, followed by 13 attempted thefts.
Police say the sharp decline is due to one thing: Officers arrested one boy several days ago. With one kid off the street, thefts dropped by almost half.
The camera can also read plates covered in muck, added Safioles, explaining it senses the indentations of the numbers and letters of the plate as well as the paint.
One system costs about $25,000. Police are looking at getting only one and installing it over the next year.
What they won't do, according to Kehler, is chase the stolen car.
Instead, they can direct other police cars ahead to intercept the stolen car at a safe time and place to catch the thieves before they have injure someone or damage other vehicles and property.
The system is used in Vancouver, said Sgt. Gord Elias of British Columbia's Integrated Municipal Provincial Auto Crime Team (IMPACT). Vancouver has used the cameras for several years and credits them with helping to reduce auto-theft crimes.
Elias said an unmarked police car installed with the system blends into traffic and less visible to thieves. Covert police cars are brought to intercept the car when the time is right.
"People have no idea," he said, of the thieves.
The car with a camera can also prowl hot spots of the city known for high rates of auto theft, including parking lots where cars are frequently stolen (Polo Park and St. Vital shopping malls are two of the worst spots in Winnipeg) in the hope of catching a thief in the act.
Young thieves often steal up to five or more cars in a day. Usually they dump a car close by the next car they want to steal. Elias also said a police car equipped with the camera can be parked on the side of road at a street or bridge connecting one part of the city to the other. Once a stolen car is identified by the camera, officers can radio ahead to get police to set up a road block.
"You're only limited by your imagination what you can do with it," Elias said. "It's a piece of the puzzle. Like any puzzle, you have to put the pieces all together to tighten the noose around these guys."
In Winnipeg, Kehler said police aren't going to discuss tactics they plan to use.
He said the system can also be used to sniff out uninsured vehicles and suspended drivers, but that part of enforcement isn't planned for Winnipeg.
The system was announced Tuesday by Mayor Sam Katz in conjunction with Premier Gary Doer's pledge of $500,000 toward doubling the stolen auto unit by five additional officers.
The purchase of the camera and the additional provincial funding for the stolen auto unit only came together over the past few months -- before a jogger became the victim of a deliberate hit-and-run with a stolen car on Wellington Crescent March 8.

Here's how the system works:
* A police car will be equipped with two special cameras, which are hooked up to an on-board computer.
* Each day, a list of stolen vehicles and their licence plate numbers will be uploaded into the computer.
* Once on the road, the cameras will scan each oncoming vehicle and each vehicle in the right-side lane or parked on the right-side curb.
* Cameras then automatically read the licence plate of each of these vehicles and compare their plates with the list of stolen vehicles in the computer.
* When a match is found, the plate and make and model of the auto are verified. * Depending on the situation, police can then take any number of actions.
