American company win the �150m contract to run the UK census,CIA have total access to all these UK records?

Has it not occurred to anyone that the UK Census only completed by people like me who don't give a stuff what the totally inept CIA make of 50000000+ facts you give them. I trust the would be terrorists etc. decline the privilege of providing the information if they thought it might impinge on their intended operations. On the other hand they might comply with the legal requirement to complete the census. So now the CIA have nearly 60000000 suspects precisely what will they make of that? I daresay some department in the CIA has academic prodigies who make career paths out of this type of database. Good luck to 'em
