Cops Arguing About Lidar

Too funny, But at the same time very informative!

Cop:

"Not taking into account that alot of LEO's are not even certified to use Lidar. Lidar can be taken down in court on reliability issues alone. Lidar is anything but a reliable speed measuring device. Lidar suffers from a major problem called the "Slip Effect". See the video links below, the same guns in question are widely used in Canada."

How about LIDAR also being handheld most times.....and aimed like a gun. Just a twitch of the hand could be a few hundred feet of movement at the target end of the laser beam. Do shooters ever miss with guns? Same deal with LIDAR
 
For frig sakes I expected to learn something new about LIDAR instead it is an article from 2008! LIDAR uses light emission 300,000 km/s vs a pistol muzzle velocity ave 360 meters/second so unless the officer is having a seizure (thus being too occupied to be concerned about any violation) in his car a twitch is not going to give an errant reading.
 
Does Ontario use LIDAR, or KA in most circumstances? In my research they usually say "depending on their budget." Most Canadian cops seem to have the best of the best.
 
They use LIDAR, Ka-Band. Xband was delisted years ago for police use and now that frequency is used in commercial and residential electronics ie cordless phones K-band will be the next to go. Equipment is budgeted for and sometimes obtained through government/community safety funding, Insurance Bureau of Canada, other private sources and corporate donations. Smaller forces piggyback on the OPP corporate contract rates for police radar and other equipment...RADAR equipment and training in Ontario must meet approved training standards as set out by the government and the Ontario Police College that trains most of the radar instructors who in turn train police officers. Police organizations as part of their policy and procedures must also establish their own standards that should closely mirror the government standards for training and use.

Sure it will. A twitch could easily result in a few beams hitting hood, then a few hitting windshield, then a few hitting bumper etc....gives a drastically incorrect reading. with less than 300 pulses per second, where on the target the beam is focused matters.....and it is imperative that the beam's footprint, which can be as big as 3 sq ft at 300 meters away, remain constant and not move about on the target. It is called sweep error, and evidence has shown there can be as much as 155 kmh error from sweeping from windshield to licence plate and back again.
This alone has been used in court to beat LIDAR.......not to mention, who says a cop's aim is perfect? Is he a trained sniper? Are the gun's sight's pefrect? Any handheld precision instrument is subject to human input and error....at least a radar has a wide enough beam that any small movement of an officer's hand or vehicle can be absorbed as the target would still be completely in the beam's footprint.

Even radar is very unreliable, but this never seeems to come up in court. If a vehicle larger than yours is anywhere in the path of a radar, it can give false readings. Even a roadsign anywhere between the radar and the target vehicle can give false readings. Isn't there roadsigns at the edge of just about every town? Ever hear of people baing ticketted at the edge of town where speed limits drop?
Do some research....even the manufacturers of LIDAR and radar explain there are tons of instances where false readings can occur.

don't worry, is a waste of time discussing with him, let him be right if he wants do, whatever he says is always right
 
The word "sniper" is a apt word to use as in a prior post. See the sneaky bastards here:

When you type "can lasers" into Google, the zeitgeist shows:

can lasers give you cancer
can lasers damage your eyes

...etc. Lasers are controlled by the FDA is the states as they can have an effect on the human body. I'm wondering (and if there are any lawyers on here could back this up) if this technology could be done away with as the officer is pointing a weapon at you that can have health consequences according the FDA.

If there are any lawyers on here, could his be argued on a grand scale?
 
No the police LIDAR is invisible in the infrared spectrum and will NOT cause damage to your vision while you are driving your car. This would be viewed as an unlawful and unnecessary use of force, Which would be illegal and open, not only the officer, but the organization and government to civil liability and possibly criminal sanctions.

However this is not to say that police might not deploy a tactical strobe of visible light laser that could incapacitate an unruly mob under the right circumstances...

There are many types of lasers. Personally I like seeing sharks with lasers...

Rubbish ... I've got a laser gun and any child or simpleton can use it. The software requires a series of consistent measurements or it will not give a speed reading ... handheld is much harder and the target has too be closer than a tripod shot but if the beam shakes there's no reading....

The newer guns are even better with high quality optics to keep the beam narrow and easier to read

true, even a little bit of movement on the operator part causes an error and therefore no reading.
