Stop with the bullshit. Those people were rioting, looting, and burning. They weren't "peacefully protesting" which is all the First Amendment allows. They were armed and there to commit crimes in the chaos they were there to create. Citizens have every right to arm themselves against widespread lawlessness and violence these people assembled there to perpetrate.
A fundamental premise of juris prudence is impassionate persuit of The law....and for good reason! Can you cite the ways in which that is important and why you are not pursuing an impassionate view of the matter?
My personal feelings(your too) and my personal opinion and beliefs(your too) play no role in this case. It does not matter what you think.you know and the same goes for me. That is a fair system.
Wouldn't you agree?
