A weird analogy. The kids at the Littleton school (Columbine) weren't exactly tempered 5-year olds. If you were outmatched by a couple of punks with fully automatic weapons, I'm sure you'd be cowering behind an object too.
"If you were outmatched by a couple of punks with fully automatic weapons, I'm sure you'd be cowering behind an object too."
Are you trying to imply that "fully automatic weapons" were used by the Littleton shooters?
This was clearly not the case.
They were outmatched only in resolve - the cops at Littleton were more interested in the safety of the police than in the safety of the students. We have police and SWAT teams to take these types of risks, not wait to go in until the shooters shoot themselves.
