I think he only needs reasonable suspicion, which from a practical standpoint means just about anything.
” only needs reasonable suspicion”
You’re probably right but, again, we’re talking about a guy in his driveway.
Also, HAD there been reasonable suspicion, the cop would have stated so, e.g., I have a relative who was walking down the street in LA late at night - cops, responding to a robbery complaint, detained him and asked for ID, etc. Whole rigamarole.
But they did tell him they were responding to such complaint.
Not the case here, which is why everyone is jumping on you!
reasonable suspicion,...
Reasonable suspicion is a standard used in criminal procedure. It is looser than probable cause. Reasonable suspicion is sufficient to justify brief stops and detentions, but not enough to justify a full search. When determining reasonable suspicion, courts consider the events leading up to the brief stop and a decide whether these facts, viewed from the standpoint of an objectively reasonable police officer, amount to reasonable suspicion.
Courts look at the totality of the circumstances of each case to see whether the officer has a particularized and objective basis for suspecting legal wrongdoing.
