I also noticed (on at least one flight) that as the boarding passes were read by the scanner it would randomly(?) select people to be screened.</font>
AA uses these scanners, and US does not. So AA knows exactly who is on the plane and who isn't, in real-time. Since US doesn't scan, does the gate agent run back and enter everyone in as soon as the line clears? Otherwise, how do they check boarded passengers vs. checked baggage, etc.?
