I'm Sure It's Just an Isolated Incident

I mean, just because you find five French-Moroccan muslims breaking into a courthouse at 2 in morning, and they had photographs of infrastructure, malls, water systems and public buildings in their RV, that's no reason to be concerned is it?  No, I'm sure it's just an isolated incident.

Five men in their twenties, described as French-Moroccan Muslims, are being questioned by the FBI Joint Terrorism Task Force and by officials of the Department of Homeland Security after they were arrested inside the 120 year old Bexar County Courthouse in downtown San Antonio shortly before 2 this morning, 1200 WOAI news reports.
......
"They got travel documents, parking passes, they have been all over the country," one law enforcement officials who asked not to be identified told 1200 WOAI's Michael Board on the scene. "A lot of photographic equipment, a lot of documentation equipment inside their vehicle."

And I'm sure just because a "middle-Eastern looking" guy named Ali Reza Shahsavari runs down the aisle in a plane shouting

“You’re all going to die,” a man dressed in black screamed at passengers Tuesday afternoon. “You’re all going to hell. Allahu Akbar,” .... 

there's no reason to think something suspicious is going on there.  No, siree.  Big Sis Janet Incompetano is on the job. 

What do both of these stories have in common?  In both cases, the authorities made sure to let us know terrorism was not suspected.

FBI Special Agent Mark White, based in Dallas, said the event did not appear to be an act of terrorism. He described Shahsavari as a U.S. citizen who might have experienced an episode of mental illness. (note:  "an episode" of mental illness?  not a life of mental illness?? - GB)

I'll leave it to you to determine how it affects your training and other preparations.
