No, but I am suggesting which databases people should or should not be able to make. Or more specifically, which databases the police should or should not be able to make and access. "Who was seen where and when" isn't particularly privacy-violating. It's the search capability that is. This is especially true when it's targeted at a particular person - I'm not that worried about the police finding people who were in a particular area at a particular time. They've had that power for a long time, through canvassing and other traditional detective work. What I'm worried about is giving them the new ability to quickly and cheaply compile a list of everywhere someone has been and when.
