If Obama uses violence against US citizens to protect illegals -- which is illegal for him to do -- things will escalate very quickly, I'm afraid.
He needs this unrest to detract from his failures.
Obama is very vindictive. He's no different than the nuts on DU. We've all read their fascist solutions on how they would deal with those that don't agree with them.
He would love to use his power to force public opinion with an upcoming election.
As far as using riot police in Murietta, so far the only people who have been arrested are the pro-immigrant supporters. It also just happens that a lot of those people were bussed in from Los Angeles. La Raza is the group behind this.
This is a government sanctioned invasion, brought to you from the Soros' funded open borders crowd, and which Obama (who considers the USA an Imperialist nation) also agrees with the open border meme.
