I didn't read the article, but all your excerpt says is that 2 off-duty police used their guns. How is this related to regular people carrying guns? Edit: One used her gun and one just restrained him.
"Off duty" is regular people. They were not functioning as police-people, but rather in the same capacity as any "regular" person after work hours. Any armed citizen could and likely would do the same.
so are cops. He wasn't just a movie goer. i dunno why I'm responding to you actually, nevermind, carry on.
Are all these threads really necessary? Heaven forbid we have a poor opinion on firearms, their feelings might get hurt.
