The infamous sound cannons, which the government initially claimed the Serbian police does not have, were procured through the company "Romax trade." This company and its owner, Goran Rodic, have a license to trade in weapons, access to "highly classified information," and deal in various goods—from plumbing installations to Wi-Fi equipment. They are linked to Deputy Prime Minister Aleksandar Vulin, and it is known that Rodic was one of the financiers of Dragica Nikolic’s foundation.
