Detective Work by The Boondocks

US police put hip-hop under surveillance. I'm pretty sure The Boondocks was making fun of this ages ago. I guess it could sort out those who are "Keepin' It Real" from those who are just carefully constructed studio products.

Although when it says:

"They were trained what to look for in the lyrics, what to look for when they go to hip-hop concerts, what radio stations and TV stations to monitor to keep abreast of any rift between these rappers."

You do have to just ruefully shake your head and hope someone has a whisper in the right persons' ear at some point. May be something like "You know Eric Clapton never did actually shoot a sheriff..."
