"Foreseeable" ... YES, "Predictable" ... YES. .."Self inflicted" ... NO WAY! 
Democrats (i.e. Chuck Schumer, Nanci Pelosi,  Racist Maxine H2O , Obama along with Soros) have created and fueled the "Hate and Discontent" ,Anti Trump Resistance Movement.. All of the afore mentioned must take blame for violence from the BLM, Move On, Hollywood and a cadre of press and media instigators. Communist Bernie Sander's  and his followers are not beyond violence either.  Collectively, they are un-holly mix of communist anarchists  who are inclined towards intimidation and violence. Pelley,  a CBS  democrat propagandist is small cog in the big wheel of democrat obstructionism.
