I believe that mobile camera vans use laser in certain parts of the country and some other ones use radar?at least thats what i have seen on here.This could get expensive coz i may need both types of jammer. gonna get them though.cant stand the thought of gettin nicked again by lard arse scuffers sat in the back of a van eatin all day but believin theyre doin a worthwhile job whilst there are a load of illegal immigrants hopin over a hedge behind them (unseen) and theres muggings and stabbings going on and theyre too sh*t scared to do anything.I have had mates who have phoned the law to report theyre cars gettin nicked but theyve never got anyone to send out.Too busy,no one available coz theyre sat in the back of a van zappin people. I remember my old man sayin "once a copper never a man" God i really hate em with a passion
