I haven't figured out why TFR's exist. How are they supposed to
protect the President and/or whatever else?

That's the general principle.

Does the Secret Service and the FAA really think that just having a
"no flight activity" within an imaginary circle sixty miles across
will really stop a determined assailant?

The FAA ain't running the circus. I suspect that the Secret Service
feels that by keeping all (or at least) most friendly traffic out of the
area, it makes it easier to spot the unfriendlies.

The TFR's used to follow the president around for certain appearances
but they were MUCH smaller than the recent oens.

Are the airliners prevented from flying within the TFR? If not, can
someone explain why not? It wasn't a lightplane that caused the
collaps of the WTC.

The argument (laughable) is that air carriers have gone through a more
rigorous security procedure and aren't a problem.
