'Reasonable cause' under §837 means which of the following?
Explanation
The 'reasonable cause' (often called 'probable cause') standard from People v. Ingle (1960) 53 Cal.2d 407 is: a state of facts that would lead a person of ordinary care and prudence to believe and conscientiously entertain an honest and strong suspicion that the person arrested is guilty of a crime. This is far more than mere suspicion (a) but far less than the criminal-trial 'beyond a reasonable doubt' standard (b). Purely subjective belief without an objective factual basis (d) is insufficient and exposes the guard to false-arrest liability.
