Let’s say you are testifying in a US court and are asked a question which would incriminate you if you answered truthfully, so you plead the fifth. Provided the question was specific enough, does doing so then give law enforcement probable cause or reasonable suspicion to search your person or your property, or to arrest you?
Example: You are asked, “Do you currently have child pornography on your home computer?” and plead the fifth. Can a police officer use this refusal to answer as the sole basis for obtaining a search warrant to seize your home computer?
Another example: You are asked, “Do you have any illegal drugs upon your person?” and you plead the fifth. Does this alone entitle the court to arrest you on suspicion of possessing illegal drugs, or to search you on the spot for same?
A less specific example: You are asked, “Do you currently have anything of an illegal nature in your home?” and you plead the fifth. Though no specific crime was mentioned, does this give the police grounds to obtain a search warrant for your house?
As always, if answers vary by jurisdiction, please let me know.
