Does Tanzania have special unit for the protection of the President? (Presidential Protection Unit, PPU)? Or is "Usalama wa Taifa" one big PPU? Apart from PPU duties, does 'usalama wa taifa' have anything else THEY know they are supposed to be doing? How do we gauge SUCCESS of those non-PPU duties? For instance, Uganda wana PPU, kazi yake kumlinda Museveni na walio karibu naye. This frees up the rest of usalama wa taifa uganda. Kwa mfano, Uganda wana counter-espionage unit ambayo ina operate outside Uganda. Kenya usalama wa taifa wao unapelekwa kisomi zaidi. Niliona tangazo la kazi ya usalama wa taifa kenya KWENYE GAZETI.
