And tell me how Colorado gun law was a hindrance to your dream.
It seems unfortunate to me that even though most of Colorado citizens are privileged to have the legal right to carry firearms, (most people in the world don't have that right) none of the ones at the scene availed themselves of the opportunity to be able to defend themselves or others...
Upon googling, i also see that unless an American citizen is from a US state with which Colorado has "reciprocity", even a citizen who is legally allowed to carry a firearm in another US state, she is not allowed to do so in Colorado:
Colorado gun laws
That restriction seems to apply even to American soldiers.
Also, looks like the Colorado and other US states' laws prohibit legal firearm carriers from carrying in places where mass shootings have already taken place in America, such as schools and universities.
