When the person and/or place is considered a national threat under the Anti-Terrorism Act. In other words if they say they thought you might be a terrorist or affilated in some manner to such people or places fequented by known terrorists or even suspected terrorists. Or if there is propapable cause I.E. pills spilled, smells like marijuana, blood is seen, ect. So basically you need to ask if you are under arrest the second that you are requested to ok a search of person, property, or home. If you are not under arrest you can request that the officer provide you with a search warrent-if you yourself dont sign it, it has to be signed by a judge. Depending on what time of day it is that can take anywhere from 15 minutes to 8 hours.
