What circumstances are sufficient to justify the arrest of a man and a woman for possession of a firearm?

Of course, the circumstances quickly burgeoned from those justifying a detention to justification for an arrest. As the red light on the police car was activated, a third black man appeared in the rear seat. Moments later, a handgun dropped out of the front door of the stopped car. In addition, once the occupants were out of the car, the officer saw several objects "in plain view" inside the car, including a bandanna, some gloves, and a number of quarters on the back seat. The sum total of the facts known to Officer Gray was adequate to ". . . lead a man of ordinary care and prudence to believe and conscientiously entertain an honest and strong suspicion that the (defendants were) guilty of a crime." (People v. Galosco (1978) 85 Cal.App.3d 456, 461-462, 149 Cal.Rptr. 407, 410.) The arrest of defendants and the search of the car were proper. (Id.)
