This story should really need no explanation. Two quotes:

"I asked her when you became a police officer didn't you take an oath to protect and defend the constitutions of the United States and the state of Colorado. She said, 'I guess I did; I can't remember.'

and:

[Judge Patterson claimed that] precedents of the Colorado Supreme Court and even the Constitution of Colorado are not applicable in Denver, because Denver is a home-rule city… [Assistant City Attorney Paul Puckett claimed that] "The Constitution has no force or effect in Denver, because this is a home rule city."
