Justin Carter is just an ordinary teenager.  That's what he says.  You see, when he's on his Facebook page he likes to crack jokes - about killing kids.

Carter was recently arrested and charged with terrorist threats for this eye-popping blog:

"I’m f—ed in the head alright. I think I’ma [sic] shoot up a kindergarten and watch the blood of the innocent rain down and eat the beating heart of one of them.

Then he made it clear that his intentions were nothing short of humor by striking the "JK" (just kidding), and "LOL" (laugh out loud) keys.

The judge presiding over Carter's preliminary hearing wasn't "LOL", nor was he "JK" when he set bail at half a million dollars, which some people felt was far too excessive.

Enter a follow-up petition by Carter's mom, which saw over 100,000 signatures, aiming to get her son released.  Well, it didn't work the old fashioned way, but the notoriety caught the attention of someone sympathetic to Carter's cause.

Thanks to a very generous, and not to mention a very wealthy anonymous donor, who shelled out that $500,000 in bail, Carter is a free man awaiting his hearing on July 16.

A hard lesson to learn indeed, because nothing in his past suggests this kid is a danger to society, but with the intolerant climate of today's youngsters taking their horrific fantasies from the mind to the street, the courts are wary of becoming soft on potential powder kegs.

Justin Carter turned down a plea of eight years in prison on third degree felony charges - which could have been reduced to about 5.5 years with good behavior.  If convicted, he likely faces a minimum of 10 years behind bars.

Don't know if he deserves to be sentenced to time when you consider drunk drivers can kill people (oh, excuse me - "involuntary manslaughter" people), often multiple times, and get no more than six months to one year in prison for their first infraction, then a slap-on-the-wrist three to five for act number two.

Here's how it all went down:
