You probably should have called the police when you first became suspicious. Give a detailed description, direction of travel, and recant the crimes commited in the neighborhood. Having a carry permit does nothing more than afford you some comfort while being a good witness. If someone makes you suspicious... there's probably a good reason even if you cant put your finger on the reason at the time. If the police were called forst they may have been able to ID him. Maybe he's wanted or at least he'd know that he was burned in this neighborhood. And if there was a break-in the police would have had someone to look at for the crime.
