President Donald Trump and Republicans in Congress rolled back a gun regulation last year that would have restricted some people with mental disabilities from buying guns. Now, this story isn\u2019t about gun control, but the law they used to erase that rule and 14 others last year. It\u2019s a tale that goes back decades, and it starts in Kenya in the 1960s. Along the way, we\u2019ll meet a man in a white suit and an army of used car dealers. This story is also the last episode of our second season, all about who writes the rules, who gets to unwrite them and who gets written off.
