The war on our police officers

Obama's constant tirade accusing white police officers of racial hatred has reinstated the racial tension and hatred from the 1950's and 1960's. Now the killing of white police officers is happening constantly. I don't think that Obama will be happy until there is open warfare in our streets like any third-world country. Could this be Obama's objective? Could it be that he wants to declare martial law once the situation gets totally out of hand so he can declare himself as dictator? One thing is blatantly clear. Obama has done more damage to our country in his two terms as president than would have seemed possible just 8 years ago. Combine this with his goal of permitting anyone to enter our country without restriction. Could it be that he wants the terrorists to have unfettered entry into our country so that they can commit any acts of terrorism they desire while our police are put into the position of fighting for their very lives?
