Are (lasers) green/ red legal for EDC ??

I was told in CCW class that I might not want to keep a crimson trace red laser in my EDC . That the local prosecutor may use that in adverse of a self defense claim as it’s illegal to point a laser at another physical person . Has anyone every been told this or heard of a self defense claim overturned because of one ? Any info helps thx via /r/CCW https://ift.tt/3ytF7BR
