I wrote about this back in March:
It’s easier than you think to create your own police department in the United States.
Yosef Maiwandi formed the San Gabriel Valley Transit Authority — a tiny, privately run nonprofit organization that provides bus rides to disabled people and senior citizens. It operates out of an auto repair shop. Then, because the law seems to allow transit companies to form their own police departments, he formed the San Gabriel Valley Transit Authority Police Department. As a thank you, he made Stefan Eriksson a deputy police commissioner of the San Gabriel Transit Authority Police’s anti-terrorism division, and gave him business cards.
