Does anyone know who this is?

He has been following this petition like others but I don't know him and law enforcement is looking to find out who this is? Any ideas? 

As a jewish student in America, my family always warned me that despite my constitutional rights as a U.S. Citizen, that the opposing site will always try to use everything against me. 

Thankfully, the FBI took over the investigation and all the videos etc. so I can just focus on posting updates on the daily felony vandalism now.
