First of all, welcome to the board.
Second, take a quaalude, dude - you are way too high-strung about this.
Third, settle down, take a look around and you will find about eleventy-million years of automotive and Intrepid experience around here.
Here's what I know about radar and laser from research I have been doing:
Your original post talked about laser being 1mm wide. Perhaps when it leaves the gun, but by the time it gets to your car, it's about 3 feet wide - still much narrower than radar.
Whether it's 3 feet wide or 1mm wide when it hits you car, you're generally toast is a laser DETECTOR goes off.
A system like the K40 Diffuser Plus is legal and is effective in scrambling the laser signal before it's returned to the gun. Dunno about license plate covers...
For laser to 'work' for a cop, they need to be within 10 degrees of dead-on to the car.
Radar jamming is illegal in 50 states.
If you are alone on the road and a cop 'bursts' the radar, you are toast.
If there are other cars on the road and a cop is 'bursting', a good radar detector like the K40 can detect the scattered signal from the cars ahead because the radar is so wide.
I have no clue about the VASCAR.
I'm not plugging the K40 stuff - I'm just leaning toward it based on what I've been researching.
Once again, Jer_BEAR_bluez, welcome to the board. Sit back and enjoy the ride....
Oh yeah - read your sig!
