From your link:
In 2003, the state legislature and the governor deemed that the power to address gun violence in Colorado through laws SHALL NOT be in the domain of the affected communities,
rather it should rest only in the hands of the state. By this legislation (SB03-25),
all of the ordinances on this list have been declared unenforceable.
Note from the link that the city of Denver is contesting the State Law and judgment is pending? Aurora seems to be also unfriendly to concealed carry permit holders. Combine that with a theater chain that may prohibit concealed carry and you have a situation in which most CCW permit holders would simply leave their weapon at home on movie night, or in their car, or fear taking action due to legal consequences, unless the shooter was actually pointing his weapon at them or a family member.
Violence is increasing; the need for self-protection and to protect those around us, more important. Luckily, in the state where I live, municipalities are all pretty much pro CCW. Otherwise, knowing that most CCW holders follow the letter of the law and then some, they would not carry where not welcomed.
Thank you and all for contributing,
