Well since I was the one here affected (so far no other FTers have said a word), I will tell you that the TSA had no choice but to evacuate 2 and 3 because they let some idiot go through without security. It's a nice Monday morning quarterback response to say what should have been done but no one knew what this idiot was going to do or had on him. They had to evacuate. The anger in our plane (at least by those near me) was geared directly at the guy who snuck through and the idiot guards who didn't stop him. The captain kept us fully aware of what was happening which impressed us all. The Delta crew was terrific.
