How has the security in American airports changed after 9-11?

A number of ineffective measures were introduced. None of the measures were based on any evidence that there was a plot to smuggle guns or explosives on to planes at that time. No terrorists have yet been caught at a security checkpoint in an airport.

Note that the 9/11 hijackers all had valid ID, were properly booked on a flight, and had nothing suspicious (even under current regulations) in their carry on bags. The knives they used were placed on the plane by others; they did not carry them on.

The security measures have been designed as a showpiece to make citizens feel something is being done to protect them. Meanwhile there is little or no screening of checked luggage (the easiest way to attack a plane, as seen in many plane bombings over the years). Airlines cite cost and delay as the reasons NOT to screen checked baggage.

And cargo planes are still not searched; freight shipped on passenger planes is not inspected; and none of the container ships entering our ports are screened for radiation or contraband.

The government has really not implemented any useful security procedures.

.. it went from laid-back to full-cavity .. its ridiculous .. i dont feel safer.

Security changed a lot!!!

A friend of mind just returned from a month in Egypt. He said it was a "*****" getting out of the US, but very easy getting in and out of Italy and Egypt and back into the US. No.

I don't know other than that old lady didn't have any bombs in her shoes or in her under pants.
