> Second, it would be absurd to account for extra income to say they make what you're saying.

Except it's extra income that they make by being a police officer. A business that hires an off-duty police officer for security isn't hiring them because they're a big burly-looking dude; they're being hired because they are a police officer. An off-duty officer will typically wear their police uniform while working "off duty", and can take actions which an ordinary civilian could not (like conducting arrests).
