Obama knows full damn well that these incidents are only going to escalate and he fully supports any and all violence against Trump.
That’s who Obama IS.
I think you are spot on! Zer0 knows by telling the mobs to back off he has shown the face of respectability. That takes the blame off him and his ilk. Meanwhile, the Mexican terrorist will not hear what he said. Even if they did, they will crank up the violence so they can instigate a violent response from the Trump supporters. The aim is to generate the violent response so they can denigrate the Trump movement.
