Here we go again....
Of course its all the TSA/BAA security peoples fault that some poor pilot who has had too much to drink has been arrested.....
I don't hear too many of you complaining that drugs dealers are often 'grassed' on, or people who rob banks are often informed on, why is there such an outcry if its a pilot? At the end of the day, dealing drugs, theft and having blood alcohol concentration when on duty as as aircrew are all crimes.
Personaly I have no problem with security informing police, in fact i would rather they did. If he had passed the first breath test, then there would have been no problem, he was arrested, so he obviously didn't. The report doesn't make it clear whether he was bailed to appear in court, or bailed to return to Heathrow Police stn, time will tell if he's gulity, in the meantime why have a go at people who are doing something for most other crimes you would encourage
