You can applaud the Irving ISD if you like—I think they are idiots, and whichever moron teacher is stupid enough to think this is a threat should be summarily fired and banned from teaching for life. GOD FORBID a student have intellectual curiosity...oh, wait—it IS a public school, after all...
Look how else it could have turned out. Headlines - Ten student dead fifteen injured. Earlier that day classmate who set off bomb had claimed Bomb was a clock. Teacher believed him. --- Better to be safe than sorry.
I realize that both of you may still disagree but given the terrorist threat posed by islamists, yes, it's better to be safe than sorry.
We have had more than our share of murders and acts of violence here in Texas committed by mooselimbs, so perhaps you'll understand why they get not an iota of tolerance from me.
