Don't Fly During Ramadan
It is a terrible ordeal, but for all of the other factors brought up the critical factor is that he set off an explosion detector (and clearly it doesn't get false positives often given the response they showed). Everything else (about Ramadan, being Hindi, the color of one's skin, etc) may be nothing more than decorations, and no one here knows what would happen if John Smith Anglosaxon set off the same detector in the same situation.Yes, they talked about Ramadan and his situation, and where the parking lot is around his house, and none of this should be surprising to anyone. They're using conversation to try to determine whether he's lying, gaps in his story, nervousness, and so on. Any single person they talk to will get a conversation that is individualized to the person. Reading too much into it may be misleading.This isn't intended to defend the TSA (universally reviled), or any of the other agencies, but repeatedly setting off an explosion detector is 95% of this story. The rest is just surrounding decorations.
