Pirated CD's in Cambodia?

Okay, can you help me here? In my trips to Cambodia the only CD's, Software or Movies that I saw that I suspected were NOT pirated were a couple of Christian music CD's by local artists at the Christian Bookstore in Phnom Penh. That's why I am confused that the government crushed 400,000 pirated CD's recently. According to a news story:

Movie and music piracy is commonplace in Cambodia, and many shops openly sell copies of both foreign and local movies and CDs for between USD 1 and 2 apiece.

Here's the whole story.
