I suggest you take a look at this

The whole story was a massive trolling effort buy some guy looking for humor and attention. Hispanic males are not typically members of white supremacist organizations.
The only reason the Vegas shooter hasn't been universally condemned as a terrorist is because we don't know what his motives were. Political, ideological, religious? The investigation hasn't revealed this.
You must not live in the US, because if a white guy steals a pack of gun from a grocery store, the mainstream media declares it an act of international terrorism.
