Would 'live tv' really be enough to stop them taking the shot?
When Danny is at the blown out window, Chris orders them not to take the shot because it's live on television.
I know that Chris has a no killing policy, and Chicago has a policy of not killing hostage takers but, and I can't remember if Danny had "killed" one of the officers yet, but he was still considered the bad guy at this point. They had a clear shot to end it right there and then.
There have been deaths on tv before, and the internet wasn't as massive back then for kids to search for it. If it isn't enough, then was Chris foolish for not taking the shot (obviously not knowing what we, the viewers know)?
