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.
