From Radar Busters:
Laser Jammers and Radar Jammers are illegal in the states of Nebraska, Minnesota, Utah, California, Oklahoma, Virginia, Colorado, Illinois and Washington DC. If you decide to use a laser jammer in one of the states that they are outlawed, consider getting the Blinder M-20 or M-40 or the Lidakek LE-30. The Blinder and the Lidatek are the only laser jammers made today that give minimal "error codes" to the police laser guns.
