I’ve seen city and town parks and buildings with “no weapons” or “no firearms” signs. What about them?
I don’t know about knives and other “weapons,” but RSA 159:26, effective July 2003, declares that only the state (not cities or towns) may regulate firearms, and that any city or town ordinances about guns are null and void, except for zoning and hunting. (Note: State Representative Elbert Bicknell introduced and promoted the legislation that became RSA 159:26. Bick was soon after elected president of Gun Owners of New Hampshire, and then in 2006, became the first president of Pro-Gun New Hampshire.
