Perhaps it's too early on a Monday, but the idea of increasing security to the cockpit/flight cabin seems rather futile, short of hermetically sealing the pilots in for the duration of the flight. Certainly there are scenarios in which one could think it necessary for the pilots/crew to have access to the passengers, and vice versa, and such contingencies provide enterprising terrorists the opportunity to exploit those weaknesses, which they seem very adept at doing.

Then it becomes a game of one-upmanship, sort of like the current state of affairs with computer viruses/hackers, and the network security guys who go around "putting out fires."
