the school is armed with. no excuse. no excuse at all. and i m not making one. i m just saying the whole concept of having teachers armed. it s kind of flies in the face of insanity given what we re about to report. and we re talking about the officer that didn t go in when he had a gun loaded. he had no excuse, just like the fireman went up the stairs at 9/11 but that said this is why law enforcement officers across america say they don t want military-style weapons out there on the street with civilians because they go to a gun fight and it m people with those weapons who have the firepower. during a news conference yesterday the broward county revealed that school resource deputy scot peterson had resigned. peterson was under investigation for failing to enter the school when the gunman opened fire.
