I believe it may be entirely possible that Trump and Bannon and other key members of the Trump inner circle are actively fomenting this sort of violent, disruptive behaviour, and are waiting in the wings for some sort of "Reichstag Fire" moment to suspend the U.S. Constitution and rule by emergency decree or martial law. 

In her books The Shock Doctrine and No Is Not Enough, Naomi Klein talks about how the U.S. government and military regularly use "shock and awe" tactics to disrupt, undermine, and dismantle long-established legal and social institutions, both at home and abroad, and to replace them with unelected and unaccountable corporate entities that benefit stock holders in major companies at the expense of ordinary people and their rights and freedoms. 

Klein writes at length about how this Shock Doctrine served the interests of American power in the Iraq War, and how it was used to undermine the power of poor blacks in the aftermath of Hurricane Katrina in New Orleans.
