The Atlantic reports on the two accounts of Gabriel Silverstein and Larry Gaines:

The whole episode lasted about 2 hours.  While the officers who questioned me were not overtly or personally threatening, the situation was intimidating and threatening.  I was never told details of the “profile”, so I don’t know how to prevent this from happening again, aside from talking to federal employees at all times while flying.  I am concerned that DEA and DHS now have files on me.  This distresses me GREATLY.  I am equally concerned that my plane’s tail number is now suspicious in the eyes of law enforcement.

Every day thousands of illegal immigrants flood over the border and Muslim terrorists plot bombings in Boston, but the DHS and Border Patrol have to harass civilian pilots. It is amazing how far the government will go, to not actually do their job.
