Actually, given the other frequent spelling and grammatical mistakes from the poster you've quoted it begs the question: How can I expect someone who cannot even write at a 9th (I'm being kind, more like 5th) grade level to actually outsmart dedicated terrorists? Either they aren't capable of spelling/writing at that level or are so careless that they don't even notice that many mistakes (either one of which makes me question their ability to secure our skies).

And, if this was printed in TSA-distributed literature (as a simple typo), then how can I expect someone who doesn't have enough capacity for rational, independent thought to realize that when discussing the subject matter, the typo should be corrected (or they didn't even know it was a typo) to carry out those important tasks either? It suggests a culture of "just regurgitate what we're told/shown since the terrorists have proven themselves equally repetitive" that does the traveling public far more harm than good.

It all goes to credibility, both in terms of the quality of information posted here and the quality of the job done in the field. SATTSO: Would you care to share your formal education level with the group?
