it's possible or your paranoia may have gotten the better of you. If they were investigating you for the manufacture and sale of drugs they may have been tailing you to attempt to catch you in the act.
whether it is difficult or not depends on the circumstances and yes, they may have had you under surveillance if they believed it would lead to evidence that would be probable cause to seek a search warrant or even an arrest warrant.Furthermore, someone told me the PC necessary to initiated a drug investigation and enter a dwelling was extremely high and difficult to obtain, that undercover cars sometimes wait for months outside of homes they suspect of drug activity before they are able to obtain PC.
there is no way to really answer this. Once they suspect some illicit activity they may question people. If they receive credible information that there is illegal activity ongoing in the lab that may have been adequate to obtain a search warrant. There is simply no way to guess what their PC was or how they obtained it.Does anyone have a speculation on what sort of evidence they may have needed to get a search warrant for that academic lab? Could it be a little as someone's statement, or do they need evidence of drugs or something else before they could ever do that? I always imagined it took a hell of a lot of something very convincing to put a professor in such a humiliating situation.
