SAN JOSE, Calif. (AP) — A former manager for a Silicon Valley security business that worked for Facebook testified at a sheriff's civil corruption trial that he and his company's CEO agreed to give political donations in exchange for concealed-weapons permits they needed to help guard high-profile clients. Martin Nielsen, who implicated a Santa Clara County sheriff's captain and others in the alleged bribery scheme, testified publicly for the first time Monday at Sheriff Laurie Smith's trial. He detailed how he was tasked with finding a way to get concealed-carry permits for AS Solutions security agents who were assigned to high-profile clients, the Mercury News reported. The effort followed a 2018 shooting at the YouTube campus in San Bruno in which a woman wounded three people before killing herself. The now-defunct security company's high-profile clients included Meta CEO Mark Zuckerberg.
