brazil: do banks have metal or melanin detector doors? · global voices
brazil: je, milango ya benki hubaini vyuma au rangi za watu?

according to the filmmakers, the experiment showed that the metal detector doors are in fact activated by the banks' security guards.
kwa mujibu wa waliotengeneza filamu, jaribio hili limeonyesha kuwa milango yenye vifaa vinavyobaini vyuma huwa inawashwa na walinda usalama kwenye mabenki.

there were no metal detectors or special machines that we had to pass through at the entrance of shopping centers or museums or anywhere for that matter.
hakukuwa na vifaa vya kutafuatia vitu vya chuma alivyobeba mtu wala uwepo wa mashine maalum ambazo tulipaswa kupita kwanza katika milango ya maduka, katika majumba ya maonesho na mambo mengine yanayohusiana na hayo.
