Current lasers do remarkably well penetrating smoke and dust but those things can severely degrade the laser. In my experience, from 15 years ago, is tht lasers do not work well against mirrors; they deflect and confuse them.
Good to know. I have replaced all my tin foil hats with mirror hats. Well mirrors on top of the tinfoil. We can’t be too careful.
Against a high-power laser everything, no matter how shiny, actually looks black.
