- Hiring Bad Cops November 16, 2025At the outset of his second term, US President Donald Trump shut down a database designed to provide law enforcement agencies with information on the past records of job candidates.Michael Penn
- Visible Minorities: Takaichi’s PM Election Changes My Projections October 8, 2025The recent election of Sanae Takaichi as leader of the LDP probably means Japan’s first woman PM. But this is a huge step back for Japan’s democracy and diversity.Debito Arudou
