I think it may be time to surf the internet in privacy mode. "Today, an FBI agent can open an intrusive investigation with no reason to suspect criminal activity, and any resulting information can be kept for 20-30 years, even if it has no relationship to the investigation. Similarly, the FBI keeps so-called "suspicious activity reports" that are determined to have no relevance to terrorism – but may reflect Americans' constitutionally protected speech or other activities – for 30 years in a widely-accessible database."
