We're now more than eight months into California's legalization of recreational marijuana. But there are still illegal pot shops all over Los Angeles.

On Friday morning, city attorney Mike Feuer announced that LAPD has helped his office bring forward criminal cases against more than 500 people allegedly involved with illegal pot businesses.

The crackdown comes as licensed shop owners say they're struggling to compete with the city's many illegal shops, which are selling much cheaper product by avoiding taxes and regulations.
