Ok, heres my opinion on this. Once the FBI cleared them the airline should have let them fly. On the other hand I understand how the other passengers could become suspicious. Muslims know many Americans are suspicious of them to begin with. So why say things that would raise a red flag. Anyway Its a shame this family had to be treated this way but thats where we are in todays society. The Airline would have been derelict to do nothing once the other passengers concerns where brought to there attention.
