Re: It's not a surveillance program
"Keep coming back every year" is no help. They'll just make small changes every now and then, each one individually not big enough to rouse much opposition, and in ten years you'll be there all the same.
We've seen this before. It's what happened when the US began fingerprinting tourists. Even the reassurances were the same: the immigration database was separate from any other set, they'd never be compared. What they didn't say was that this was not policy, it was sheer incompetence on their part - they were storing the data in an incompatible format - and two years later, that bug had been fixed.
