I can't think of a better illustration of the "bootlegger and Baptist" coalition supporting prohibition than the case of California state senator Leland Yee. By day, he was one of the most outspoken advocates of gun control. By night, he was apparently trafficking in illegal weapons.
Smuggling only earns high rents if the underlying goods are illegal. Who ever heard of cucumber smugglers, or dealers in the illegal cat 5 cable trade? Every time Leland Yee took another action to make guns harder to own in California, he not only got pats on the back from gun control "baptists" on the Left, but he also made his criminal friends more money.
