American Apparel is being sued in a class action brought on behalf of shareholders due to their allegedly not disclosing how their habit of employing illegal aliens could get them into trouble. In July 2009 their were raided by ICE, who found that one-third of their workforce might be illegal aliens. A couple of months later they laid off one-quarter of their workers. And, throughout it all, they've been "protected" by local leaders who don't see any problems with them employing illegal aliens. American Apparel went as far as hiring the Mexican government-linked Peter Schey to represent them.
