I am no French nor Muslim. Just like applying a job with the US federal government, they would run a security risk analysis on a person before admitting him to the service. If the risk analysis include frequent trips to Pakistan as one of the high risk factor, then so be it.
You just cannot help with some people in a country that are full of hatre. Last night I was in Times Square at night, just off from LGA, got the verbal abuse by the Hispanic spoken only Hispanic language, for no apparent reason. In the future, would I hire "those" people, including the I.I. who have so much hatre to the normal, non threatening, Americans citizens? Absolutely NOT. I will not hire hispanics from now on. None. Call me racist. But this is due to my personal experience of one group of people with so much hate to others. Why would I put myself into this situation. So do the French government. I sympathise her position and I would choose to fly CDG rather than LHR, and have a peace of mind.
