It was explained to me as follows: those responsible for security assess
all possible threats and create plans to mitigate each one. Regardless of
our opinions, small planes are indeed a threat and the easy thing to do
was
to restrict their activity within a certain distance. They are considered
a
greater threat than large commercial planes (to the mobile president) for
reasons I will not go into here. GA is an easy target for restrictions
because of GA's limited political and financial clout and the extreme ease
of clearing the area of GA aircraft.

Claiming that a truck bomb or suicide bomber can be a larger threat is
besides the point. Each separate threat has a plan to deal with it. GA
is
dealt with by TFRs. Other threats are dealt with in other ways.


Finally a reasonable explanation without whining about how we are
specifically targeted. The ONLY way to deal with this is to vote in an
administration which doesn't **** off the entire world and incite everyone
to target us.
