The school had metal detectors. The guards were unarmed. The presense of metal detectors presumes the possibility of hostile weapons. Having the guards unarmed simply puts the situation at the complete discretion of the hostile.
Two guards. Unarmed. Had they been armed (and trained and competent) he might have taken one, but not both. Instead many are dead and crippled. What the hell are people thinking? Unarmed security guards involved in weapons interdiction is an exercise in bureaucratic asininity, a public experssion of rhetorical nonsense.
Liberals kill.
These things only seem to happen in gun-free zones.
Well, the guards probably did a fine job of keeping dangerous drugs like Tylenol out of the school.
