The other interesting tidbit about the palmer lake raid is that all charges were eventually dropped. Some folks copped a plea, early, but anyone who said "screw you" to the state and held out got null-prosecuted in the end.

A bar allowing legal gambling on its premises may lose its liquor license for violating community standards or some such crap, but no crime has occurred if the gamblers know each other socially, outside of the gambling activity.

When/if the house starts taking a cut, or using the (money) gambling as a draw, then it becomes illegal for the house.
