Has anyone that travels Interstate 094 East notice the sheriffs departments locations and range when using laser. I have noticed that they are starting to place them selves in position so that the first chance you can see them is around 350-300 feet?

I have gotten lucky a few times not getting caught by laser but i got a ticket two days ago going 74 in a 55. I got hit at 280ft. Even if i had a laser jammer what are the chances to even jam at that distance?
