I am waiting for the episode that shows the unsub going free because he or she is caught because the team relies on Garcia's illegal search. I get that sometimes a victim's life is at stake and there is a decision to risk using such info, but the only time I remember the issue being addressed was the episode early on where the soccer player was kidnapped and was being held in the unsub's home. They went in without a warrant and were worried because they would not have been able to use the evidence they found if the girl wasn't there. Because she was, they argued that the girl was in danger and they didn't have time to get a warrant in time to save her life so the search was valid. These days, in almost every episode Garcia looks at people's bank records, medical records, employment records, etc., all without the consent of the person and without a subpoena.
