Wondering if the "strobe lights" they are referring to are amber strobes not uncommonly used by the construction industry.Did anybody ask if he was a sharpshooter? After all carrying a pistol in a public area at a great distance from Air Force One or the Presidents secured area is hardly a direct threat. While I understand that in the name of "National Security" it may be necessary to investigate the incident I am not yet seeing anything that would warrant an arrest. After all he may have had legitimate business there. The story is too breif to properly make any judgements at this time but does make one very curious.
