Does Colorado law dictate what dealers can charge for private sale transfers?

[Great-Kazoo]

A law that is not enforced should be nullified.

As well as the politicians who propose such laws.

As well as the politicians who propose such laws.

Each legislator is allowed to introduce 5 bills. Most politicians are seeking re-election or further offices. In order to do that, they must get publicity as fast as they can. So, they see their duty as they must introduce 5 bills and get them in front of the public.
Fortunately, most of the bills die in Committee or do not pass.
But, given the volume of the legislation, the inattention of most politicians to anything beyond their own interests, and lack of publicity; a lot of laws get passed that all have unintended consequences.
I don't have the answer to resolving this conundrum, and I haven't seen any political systems that are better.
You would have to change human nature.
