Now that you mention it I had to double check myself.
The Shaffer on the roof is probably not Ben but likely Matthew Shaffer. He’s an Officer in the Cecil Township Police and could also be a member of the Washington Regional SWAT. Sidenote: The Lieutenant at Cecil, Guy Kuzak, is the Commander of Washington Regional SWAT.
Could only find an image of Matthew Shaffer from 2017, give it another 7 years and that could well be the one on the roof in my opinion.
