Your question has nothing to do with FIREARMS.
yes
It is not a requirement to show RADAR readings in Illinois.
No they do not. There is no state where it is a legal requirement.
They have to show that it is has been tested and is functioning properly.
no
No the law even says they do not have to show you the gun what so ever.
No, he played the Radar o'Reilly chacacter in a pilot episode for the show W*A*L*T*E*R, where radar was a police officer for the city of Cincinnati.
Since 2010, There are no states that require the officer to show the radar or laser results. Virginia used to have a law, but it has since been repealed. Some departments have policies that allow or require the officer to show you the results. Most states allow the officer to estimate your speed, and this is valid in a court of law.
No, They do not and they probably won't. Do not use that as your excuse in court... Because you will loose..
All they have to prove is that it was within manufacturer's specifications and calibrated properly, so when stopped by police, they don't need to show you the radar gun, when you ask to see it. An officer does not, and more than likely, will not show you what speed you were going on there radar. That issue would come up in court.
No, not on the scene. But if you go to court the officer will have to present certification as to their training to operate it, and the fact that was"calibrated."
Contacty your local police for current information.
Because it's a widespread "urban legend" that it's required. The officer is required to display the most recent calibration for his equipment only when appearing in court to testify against you, but they are NOT required to show you anything about the equipment when you are stopped on the road.
