The odd one out

This week's In Jerusalem contains an interesting article about a former staff photographer at Yediot, who made a career switch and became a private investigator for the Haredi and modern-Orthodox sector. He relates how he caught a synagogue's gabbaim stealing the cash the shul had raised for charity; how a young woman with bruises, whose family suspected she was being abused by her husband, was actually beaten up by the Modesty Patrol who discovered she was renting videos; and how Yeshivot are increasingly resorting to video surveillance to monitor conduct in their institutions.
The bit that really got me, however, was the picture of the (secular) detective 'undercover.' This is how he dresses 'when he is called in by a concerned party and must meet with other members of the community whom he is trying to help, but who might not trust him if he came in secular garb':


 

Has it occured to him they may not trust him if came in a really obvious fake beard, either?
