I do not believe that it was done on purpose, I think it's in some way a reflection of general morals and ideas of dealing with terrorism floating around in the US society at that time, shortly after 9/11.

Imagine you are the director of such a show that is about some hero that prevents terrorism. What would you make that hero do to prevent a second 9/11 to capture the audience.

Edit: What I can imagine is that 24 inspired some US officials.
