The problem with the green lasers is that they are generally more powerful than the red. They are often 20-50mW, class 3 lasers - that is bad. Red lasers are generally only 1 mW and are class 1 - that is ok except you never actually know.
Anyone one directs a laser at you can be considered to be engaging you - not in the marital sense.
I don't know what the regs say - but unlawful interference, assault or some such seems appropriate.
