I think arbitrary is the wrong word, the correct word is subjective. The decision wasn't random, or capricious as is the denotation of arbitrary. But the decision was subjective in that it's based more on instinct, bias, opinion, feeling, than it is on something objective that can be articulated in a way that it's a reproducible judgement with different particulars.

These white supremacist flare ups happen in the U.S. and there's no predicting how serious they are by casual observation. There is substantial evidence they want to establish a white ethno state, that is their stated goal and purpose.

1924, Democratic national convention, KKK tried to get their guy made the Democatic presidential nominee, it involved physical fist fights, hundreds of police had to break up the fight, it took over 100 rounds of ballots over two weeks to sort it out. The following year, 25,000 KKK in full regalia were marching on D.C. in broad daylight. https://en.wikipedia.org/wiki/1924_Democratic_National_Conve...

1984 there was a broad daylight armored trunk heist in California, $3 million bounty. Most of the money wasn't recovered but what was traced was found to be funding various Nazi organizations with the purpose of starting a civil war. One of those groups, The Order, had a hit list including Allan Berg a Denver journalist who was assassinated outside of his home, by Nazis. http://articles.chicagotribune.com/1985-01-31/news/850106068...

And an FBI DHS assessment this year that finds again, among domestic extremists, they are most concerned about white supremacists. "White Supremacist Extremism Poses Persistent Threat of Lethal Violence." https://www.documentcloud.org/documents/3924852-White-Suprem...
