I was perusing a forum somewhat localized to the Calgary area, and came across a thread regarding radar / laser detectors /jammers and their legality. The topic turned to laser jammers in particular.
The last post was purportedly made by a local cop:
I was going to respond, but didn't want to get into a debate with this fellow just in case he is an actual cop, as it wouldn't be a fair fight (I'm not that bright eh?)
It would be obstruct a Peace Officer, not obstruct justice. You are preventing me from carrying out my duties (ie jamming my Laser unit). I have had this happen twice. The LTI 20/20 Laser will produce a beam width of approx 30 cm and a distance of 1km. Ie its very accurate. If the unit reads a "jam", simply waive that vehicle in and arrest the driver. I have been a cop for 14years, 9 in traffic. I have over 4500 hours operational experience on Laser. Furthermore have hundreds of hours testyfying in court. So yeah, ill be cocky here, if you think you are gonna come past me with a Jammer and get away with it, you have another thing coming. You will be arrested, vehicle towed and Jammer seized. And for the disbelivers...... Ill see you on the streets.
I've heard the whole obstruction argument before, and I don't buy his story. Especially if you are a "smart" driver and turn off your jammer after you slow down - how would he prove you obstructed anything? A "reasonable doubt" argument could be made that he was simply having difficulty in getting a readout, which he would have eventually gotten.
Also, is he correct in that the width of an LTI 20/20 beam is 30cms (12 inches) at a distance of 1 kilometer (3280 feet)? IIRC, a typical Lidar beam is roughly 36" wide at 1000', so from a distance of 3280' it would be roughly 118 inches wide?
F it...I'm gonna challenge him! Feel free to sign up and join in...
