Until recently, CSU banned CCW permit holders from carrying concealed on campus. Please don't ask if I ever followed the CSU "law" on this one, because you all know the answer to that. They've recently come to their senses.
The CSU people are not happy about it, but given the option of facing a long, expensive lawsuit levied against them by Rocky Mountain Gun Owners (RMGO) or rescinding the ban, they chose wisely. The could have bowed out gracefully (which they chose to do) or paid a lot of money to fight it and been forced to do it anyway.
