It it'd been a bag of Bibles you can bet it wouldn't've even made the local papers, let alone the ASS-ociated press - STOP PISSING-AROUND INVESTIGATING THIS AND GO DO REAL WORK!
Bibles... or American flags. Nope, burning those isn't a hate crime. Let's put that another way: if a legitimate exercise of one's First Amendment freedom of speech is to burn a flag, then it must also be a legitimate exercise to burn Korans, otherwise, it's religious discrimination on the part of the government (for prosecuting one and not the other) which also violates the First Amendment.
