Colorado gun law

On Friday I’m going to Aurora, just east of Denver, to undergo biometric testing for my work permit.  It was in Aurora that the Batman cinema shootings took place just before we arrived.  Meanwhile, local papers and Colorado Public Radio reported last week that Colorado University in Boulder was trying to ban concealed hand guns.  A psychology teacher said that he would stop his class if he discovered anyone with a gun, which might “intimidate students during class discussions”. One interviewee agreed that guns should be banned, but gave the reason that if there were an incident, an armed student might complicate the police response.  Another said why should law abiding citizens (with or without guns) be denied psychology class?

It was all for nothing: state law over-ruled the University and upheld the right of the individual to bear arms.  Students over 21 at the University in Boulder can carry a concealed hand gun as long as they have a permit.  Strange to think of me and my fellow mature students at QM going to lectures with a gun in our handbags.  Now I know that I might disrupt class discussion or get in the way of police guns, I’m no longer tempted.

As far as I can research, gun law in Colorado is basically as follows:

“Colorado allows a person to carry a firearm in a vehicle, loaded or unloaded, if its use is for lawful protection of such person or another's person or property. [C.R.S. 18-12-105(2)] Colorado law also allows a person to possess a handgun in a dwelling, place of business, or automobile. However, you cannot carry the weapon concealed on or about your person while transporting it into your home, business, hotel room, etc.”  from http://www.colorado.gov/cs/Satellite/StatePatrol-Main/CBON/1251594549010

I need to find out what you are allowed to do with your gun which qualifies as “lawful protection”.
