I think no one has labelled anyone as terrorists. People should understand that it is for the safetly all including their own relatives. If police was suspecious then they have to do their job. They certainly must have or done something which would have raised flags. The people who are complaining should also understand that how much agony and financial losses that airline and airport must have gone through because of this , but they are determined to make sure all people reach their homes safely.
