Is Suicide a Crime??

I know this is not one of my usual lighthearted topics, but I'm (potentially) pissed.  A friend of mine struggles with depression and recently had a suicide attempt.  Now NO ONE will hire him.  It's like it's somehow been put into his records and is being seen on background checks.  WTF?? I thought mental illness was covered by medical privacy policies!  So is it a CRIME??? Is it coming up in criminal background checks??  If so, I'm about to throw a fit.  What are your thoughts??  Do you have any helpful info for me?
