As an avid shooter and owner of many different types of weapons I have to say that gun sounds in movies don't sound anything like real guns. Also, any responsible concealed carry permissions holder trains with his or her weapon in low light conditions, to be prepared for situations such as this.
The amount of teargas most of the people in the theater were exposed to was negligable, as well. Having been in the Army myself, I can tell you that it takes a relatively high concentration in a confined area to incapacitate a determined defender.

Exactly my point. Glad someone else is thinking like me. Once, a bunch of peopel criticized me for saying that guns should be illegal. Fuck them. Yeah, weapons are a real problem in the US.
