Could you, I don't know, require a license on high power handheld lasers? I see imbeciles shining what looks like 100+ mW laser pens (very cheap, very easy to get) on people.

Now, I don't like laws banning stuff, but these handheld 150-2000 mW lasers can seriously damage someone's eyes. And I'm not going to risk blindness or poor eyesight for the rest of my life because some idiot thought it looked cool.

What's a legitimate use for them? It seems to me that they exist only because "high power, fuck yeah". 50mW is enough for pointing at stuff, and you need industrial lasers to cut something.

Shining them in the sky and at people is already illegal, technically, but this is a real case where preventing purchase would be better.

I used to own a bunch of 750 - 5000 mW portable (pen, and a plugin) lasers.

Historically, I've used them for stargazing (i.e. pointing out stars for other people to look at), burning / igniting things I don't want to get near (and where I'm too lazy to remote ignite), and engraving.

And acid

What's a legitimate usage of acid? Plenty. Cooking. Engraving. Cleaning.
