I bumped into my roomate from last year today (he has a built in SR7...I think it's an sr7, it's a built in passport and he got it within the last 2 years...oh and by the way, he said his V1 was a much better detector), and I told him how I got a detector and the next thing to get is a laser jammer. Then I said that while I save up I'm gonna get some VEIL. He said what's that and I said it's so the laser gun can't get a reading. He said that back in Germany (he's german, came here 3 or 4 years ago, I forget) they just used hair spray for that. So...does hair spray jam laser?
