Bad security

We got back from Paris a day late because (according to a later announcement we received on the plane) on the morning of January 10th, several passengers and baggage had gotten onto planes without proper clearance, so all passengers in Terminal 2A had to leave the gate area and go through security again. Crowd control/contingency planning was virtually nil, with one or two people at the front of the crowd of about a thousand to "reculer", with no one else at the back of the crowd telling them to move back so the crowd had somewhere to go. Then the hundreds of passengers were not formed into a line, and so crushed to get into a single line leading back to passport and security check. So our plane was four hours late leaving, and because the crew wasn't allowed to work long enough to go to our original destination (Dallas), the plane was diverted (to NYC) for a change of crew, leaving our arrival in Dallas too late for any flight to St. Louis. Fortunately, AA paid for a room, and we left the next AM for St. Louis.
