The thing I fear, but is definitely more like a concern for me at this point, is when the other half of the nation gets fed up with this mentality and bites back. IOW, civil war.
Right now, that other side is allowing this, and trusting police can handle it. I think the other side has much reason to believe this will either fizzle out or be dealt with by police (on Obama's watch) in way that halts it if it continues for say more than a few days, and continues to get increasingly disorderly.
Yet, if cooler heads don't prevail, and people (on Left) are so sure Trump supporters are (something negative, violent) then they are tempting that to come out and confront them.
Which during time of war that we are engaged in (under Obama's watch, soon to be Trump's watch) is what I think a cooler head would realize benefits our enemies, or people that would love to see America destroyed both abroad and within. Thus, one wonders what such protests are actually about, especially when they are increasingly disorderly and violent? Does Obama allow it to grow for reasons that may not be clear, and then it gets halted by Trump? Or does Obama invoke martial law, such that the people in the protest/riots that are actually pro-America, realize then that they have no leaders at the national level who support whatever it is they are looking to accomplish through this protesting?
