Philly. I don't know if what Capone and Humphreys did was really "dry snitching" since dry snitching is "accidentally" (quotes important) snitching on people by talking out loud. There's was no accident.

What they did is usually done by people with power and connections as opposed to what we usually think of snitching which is done by people with little else to use. If anything it's worse since it's abuse by the powerful.
