Because Acosta's rights are clearly superior!!!

Boulder gun owners are dirty/bad people who don't belong.

Same reason Obama can legitimize DACA by Executive fiat but a JudgeInHawaii rules that Trump lacks the authority as Executive to rescind the same.

One thing is good, the other is bad. Goodness/badness overrides written law.

In all seriousness, we are living in post-legal, post-Constitutional society* that continues to exist because the governed continue to give their consent to lawless government.

OP's Boulder example is perfect. That ordinance stands in clear contradiction of Federal and CO Constitution and criminalizes people who have committed no crime.

Everyone went to work the following Monday. Everyone continued to pay their taxes.
