Obligatory Snopes link: Click me.
Obligatory summary for lazy people who won't read the Snopes link:
Shoplifter was not injured, let alone by "a curb," or the Marines, or whatever. He tried to steal some stuff, clumsily stabbed a marine, was subdued and taken into custody. The end. Typical boring story before the internet decided it would make a good "don't mess with Marines" tale.
