He has a Muslim background, I think, and he wasn't the only one to be part of this complaint. Wired has a write up about this as well http://www.wired.com/2014/07/five-sue-gov-over-targeting/
It really doesn't matter how many companies he's been a senior VP of - and in fact, it's kind've unsettling that this is prominent in these stories, painting him as some sort of de facto nobility who should get treatment better than an anonymous person. Guards fucked up, pinged him for taking a photo when they shouldn't have. FBI checks the story out, and doesn't seem to have progressed after that one contact, ten years ago.
'Suspicion' is just that. It's not harassment unless it's ongoing.
