Alfie Williams, a longtime Philadelphia police officer, answered the front door of his Bucks County home with a navy blue 15th District T-shirt stretched snug across his burly chest.

Since June 10, Williams has been on a weekly list, shared between the Police Department and the District Attorney’s Office, of cops who are unavailable for duty, with what he described as a torn rotator cuff from “lifting a 500-pound dead body.” Williams told a reporter that he could no longer raise his left arm more than two inches because of the injury.

Thanks to Pennsylvania’s Heart and Lung Act, a disability benefit meant mostly for police and firefighters, Williams gets 100% of his $78,092 salary and isn’t required to pay state or federal taxes on it, at least a 20% raise. A Police Department directive, however, prohibits officers who are out with Heart and Lung claims from working any other job in any capacity.

In Williams’ driveway sat a bright blue and white pickup truck, covered with logos and slogans for Exterior Solutions Roofing and Siding. On LinkedIn, Williams has a photo of himself in his police uniform, with the words “Business Owner at Exterior Solutions, LLC.”
