For whatever reason, its is my understanding (I am not a lawyer) that Boulder does NOT have the same home rule rights as Denver. If so, they would already tried this sort of thing many times in the past. There a bunch of new members on the council, and I am not surprised that the topic has reared up again. If the exceptions allowing the legitimate transportation of the supposedly banned weapons by nonresidents through the municipality, it would a least keep the stupid from impacting those of use who must travel through Boulder, but have no say in its laws.
