Agree with you up to a point, but don’t know whether makers ‘reduce power’ just because’ it’s a green laser. In passing, most reports I’ve seen of misuse in UK relate to lasers being pointed at aircraft.

You're right, though, that IR leakage from DPSS modules is a big issue. E.g. here's my cheapo 100mW green through an IR-pass filter from across the room, seen with an IR-pass webcam. I certainly wouldn't want to be waving this around anyway, but yeah.pic.twitter.com/8EQnFjVn6U

This is also why my original DPSS-module-based DIY laser projector had an external IR-cut filter in front. Also, I've noticed things getting worse. I used to have a 15mW green that actually had an internal discrete IR-cut filter, but they've been increasingly cutting corners.
