Just wondered what the rules were, I'm sure they're only type approved for use in the dry as laser and water droplets don't really mix.
There are no operational directives about using infra-red based equipment in wet weather that say it cannot be used. It isn't like a Star Trek hand-held weapon where the 'laser' would vapourise water droplets.
The only two real problems are;
1. Using it in fog, as you can't really 'prove' on video/DVD that the red dot in the sight and the laser are in-synch by 'visually' doing the tone alignment test on a medium distance fixed object.
2. Depending on the height of the enforcement vehicle, very strong winds can give you lots of error 3's = unstable targeting.
