As previously reported, Alberto Del Rio was let go by the WWE this week for slapping an employee who does social media work for WWE. The name of employee who was slapped by Del Rio has now been leaked by Dave Meltzer and The Wrestling Observer.

The name of the employee is allegedly Cody Barbierri, who is listed as the Manager of Social Media Live Events for the WWE on Linkedin.com and Twitter. Multiple reports indicated that Barbierri was slapped by Del Rio in reaction to a racist comment that Barbierri made that was directed at Del Rio. While Alberto Del Rio's behavior was unacceptable, if the reports are accurate, Barbierri does not appear blameless in this situation.

Exactly, if someone made a racist comment to you, you wouldn't just sit there and take it.
Why should Del Rio be fired and not this guy for racial slurs?

Possibly Italo-American guy making racist jokes directed at Del Rio.
Firing Del Rio for hiting the guy can be considered racism if they don't fire the other one.
Firing both would be considered racist by people because they're not american.

What can WWE do?

Depends entirely on the situation. The racial comment could have been said only loud enough for Del Rio to hear it or he possibly even heard through someone else, but the slap could have been seen and heard by others in the vicinity. This makes it he said/he said on the racial part, in which this Cody guy gets the better end of the stick, but he didn't physically strike Del Rio soooo... yeah. It's probably true though and hopefully Cody gets to join the unemployment line right next to Rio.

Totally fucked up situation all around.
