Colorado Gov. John Hickenlooper was against legalizing marijuana, but once the voters spoke, he went along and defended Coloradans' right to use recreational pot. In an interview with CNN, he appears to be opening the door a crack to the idea of re-criminalizing cannabis. Hickenlooper was interviewed for a CNN piece posted Friday that noted a rise in Colorado crime rates since 2014, when recreational marijuana went on sale legally in the state following a constitutional amendment passed by voters in November 2012.
