Kotong Cops? Call Mamang Pulis

Something I found posted along Tandang Sora Ave. corner Quirino Highway, going home from the game at G9 ... funny though why'd you call a Mister Policeman if you're reporting Kotong Cops (under-the-table-transaction police). It be like saving their own skin? It'd be best if you could expose their modus operandi through the media so they won't do it all over again.
