Sorry to derail, More info please?
Well, last year I got myself a 2W 445nm and took it outside with a friend. Right at that moment police were checking highways and several other roads near me for people speeding, which of course I didn't know about. Then when we we're walking home, I turned the laser back on for a moment, and right at that moment a police car passed by and saw the beam. It really was a coincidence as they told me then didn't spot it until they were near me. So, they asked me to come to their car and show me what I had. Luckily I thought of unfocusing the laser so much, that it was more like a bright blue flashlight rather than a laser. The policemen we're quite damn stupid though, and they would've likely blinded themselves if I hadn't unfocused it. He pointed it on his highly reflective car and even on his pants. If I had unfocused it the other way around, then he would've likely burned a hole in his pants.
After that they asked me where I got it from, how much it had cost me and why I brought safety glasses with me. I told them I got them from some legally registered Dutch site for about 40$, safety goggles included. Luckily they didn't know shit about it, cause just the safety glasses alone we're already over 80$.
After telling some more complete bullshit they decided to let me go on condition that I wouldn't use it outside anymore. They did want my phone number in case they found out it was illegal after all, but in that case I would've told them I'd had sold it already.
So yeah, that was about it. Nowadays I rarely take my lasers outside, I just use them to point from outside my window at midnight or later. Even if they would notice the beam coming from my house, then can't accuse me of anything unless they search my house. Which isn't gonna happen anyways.
