Colorado Sheriffs file lawsuit to stop new Colorado gun laws

From Fox News:

Weld County Sheriff John Cooke said he and his colleagues were "not the ones playing politics with this."
"We believe that the Legislature were the ones who were playing politics," he said.
Gun control opponents say the language in the regulations is unclear and doesn't provide safeguards to prevent people from inadvertently breaking the laws.
Ammunition magazines, for example, are easily converted to larger sizes, which the bill bans. Gun rights advocates also say the law expanding background checks doesn't provide enough exemptions for temporary transfers and that people conducting private transactions will have a difficult time getting appropriate checks.
Lawmakers allowed several exemptions in the background check legislation, including transfers between immediate family members, shooting events and temporary transfers of up to 72 hours.
State officials, including Attorney General John Suthers, have worked to defend the intent of the laws. Suthers, a Republican responsible for defending the law against the legal challenge, issued a statement Friday giving guidance to law enforcement on how the magazine limit should be enforced.
He said magazine features "must be judged objectively" and that magazines that hold 15 rounds or fewer can't be defined as "large capacity" simply because it can be modified to include more.
The state has 30 days to respond to the lawsuit. . . .
