How are terrorists monitored by the public or news when arrested?

Terrorists could have executed their plans while in the airport and could result the same casualties and damages. Why did they have to go thru check-in system if they were able to get to the airport? Therefore, could this be another fear propagated for control? Are we expecting more to come to establish planned NWO? I hope they really have genuine terrorists arrested and not make-up list of names and/or news disappeared after interrogated. How do the public monitor the events on the legal system of these people? Are they being kept or hid from the public?

Do you mean after they have been arrested?

It is more than likely we will hear everything about their trials and "new uncovered evidence" in the days to come.
