This oughta get your attention. Rick Stanley, a Colorado Libertarian candidate for U.S. Senate in 2002 , has been convicted not once but twice of carrying a firearm openly even though the Colorado & U.S. Constitution protect this practice. Here's details of the first conviction from Rick Stanleys site. Yes, it appears a bit biased, but not dishonest.
The gist of it all is this - Rick Stanley wore a pistol on his belt in a holster in Denver, Co. where a city law prohibits the carrying of arms, openly or concealed. Rick got himself arrested in order to challenge this law in court. The trial was shameful, from the jury selection ( 5 of 6 were employees of the city of Denver ) To the judge forbidding the mention of the constitutions, state or federal. The judge claimed that the home rule status of Denver made the aforementioned documents inapplicable.
I cannot say I agree with all the of the things that Rick believes. But i do admire his courage in getting himself arrested in order to challenge this law.
