Colorado has officially adopted a "red flag" gun law, but Eagle County Sheriff James van Beek believes the controversial legislation is an overreach.

The law -- which didn't receive a single Republican vote in the state legislature -- allows firearms to be seized from people determined to pose a danger.

Dozens of county sheriffs had vowed not to enforce the law, with some local leaders establishing what they called Second Amendment "sanctuary counties."

Although he stopped short of that, van Beek has slammed the law as a well-intentioned but "ludicrous" throwback to the 2002 dystopian film "Minority Report."

On "Fox & Friends" Monday, van Beek said the law encroaches on citizens' rights because their lawfully owned weapons can now be seized without due process.

He explained that the legislation, approved by Gov. Jared Polis (D), allows family, household members or law enforcement to petition a court to have guns seized or surrendered based on a showing that someone poses a danger under the "preponderance of the evidence," a civil standard which means that the defendant is more likely than not to be a threat.

"I just became very, very concerned because the way they went about it. It was supposed to be for mental health, it was supposed to be for taking care of people," van Beek said. "They went about the process totally backwards. They went after the people's rights."
