I don't see any mention of mearly carrying or transporting a weapon listed under DC as a chargable offense....the DA would have to prove intent or "violent tumultuous or threatening behaviour" to make it stick, IMHO.
They can, of course, charge you with anything I suppose......
(a) A person commits the crime of disorderly conduct if, with intent to cause public inconvenience, annoyance or alarm, or recklessly creating a risk thereof, he:
(1) Engages in fighting or in violent tumultuous or threatening behavior; or
(2) Makes unreasonable noise; or
(3) In a public place uses abusive or obscene language or makes an obscene gesture; or
(4) Without lawful authority, disturbs any lawful assembly or meeting of persons; or
(5) Obstructs vehicular or pedestrian traffic, or a transportation facility; or
(6) Congregates with other person in a public place and refuses to comply with a lawful order of the police to disperse.
(b) Disorderly conduct is a Class C misdemeanor.
(Acts 1977, No. 607, p. 812, §5525.)
