Why especially public transport?

Well, when you physically assault someone on public transport, at least there's a lot of witnesses present who can testify against you?

Or for you. If nobody saw nuthin...

Because I don't like the idea of someone sitting in front of me and filming me in a situation where I cannot move.

“Hey Meta” gets “OK Glassed”.

Violence isn't the answer. Handheld IR/non-visible-wavelength LiDAR systems that permanently fry CMOS image sensors are.

If state laws permit the capture of light, let them capture light. Light has no spectrum allocation laws, no license required to emit, and as long as you're not disturbing anyone (e.g. with deliberately obnoxious use of visible wavelengths), you're not breaking any laws.

LiDAR operators do not have a legal duty to protect image sensors around them.

As much as I'd like a quick hack to disable raybands recording me - that feels like a pretty slam dunk case of destruction of property.

Just attach a camera to your device and say you where recording in public just like them, no seam to have an issue with that. Your system was just measuring the distance to the target using lidar :)

You're still responsible for damaging people's property even if you have a super clever reason why you totally didn't intend that to happen :)
