7:25AM Jog/Walk- Private Property Question

No suspicious activity to report.

Saw a neighbor from F street on a newly constructed house lanai which clearly has a "Private Property-No Trespassing" sign. Then he proceeded to the oceanfront.

Question: As a person on patrol, should I have asked if he had permission to be on the property? If not, remind him that he is trespassing or just leave it alone because I know the individual?
