It seems to be widely accepted that the margin of error for radar is 1-3 km/hr. Does anyone have a link or case law for this? I can't seem to find it in the manual for the Decatur Genesis.

I have a trial tomorrow for someone charged with stunt and speeding, 52 km over, so obviously the 3 km is very important.

As it happens, when I was preparing for the trial today, I discovered that there is no mention in the disclosure of what brand or type of radar was used, nor was there any indication of it being tested before or after the shift. The only mention of radar in the disclosure is one sentence in the brief that says "once I saw the vehicle in front of me I activated the radar...". There is no other mention of the radar at all.

Thank you in advance.

you asking a little late for this. But the older units are plus/minus 3, do a google search.....do you disclosure as to which unit was used to catch you? This is a huge step...........if you have not then ask for a continuance to perform more research....you may or may not get it.......google like hell now.....which juristiction were you in?

There is no mention in the Disclosure as to what type of radar was used. The only mention of the word radar is in the brief, but no mention of what type it was, or anything else.
