Syrian rebels in the city of Aleppo have executed a teenaged boy, believed to be either 14 or 15, for insulting the Prophet Mohammed in front of his family. The boy has been identified as Mohammed Qatta.
The rebels heard his comment ("Even if Mohammed comes back to life, I won't,"), kidnapped him, beat him, put him on trial, convicted him and shot him.
Although it is not known which rebel group killed Qatta, Aleppo is run by rebel groups affiliated with al Qaeda.
As horrible as the Assad regime is, this is a pretty compelling reason for the U.S. not to arm the Syrian rebels.
If we do, it could make Benghazi look like a Sunday school picnic.
