Because the mainstream media didn't cover these events fully, right-wing extremist influencers were able to control much of the online narrative. https://www.yahoo.com/video/rioters-set-fire-federal-courthouse-162333860.html
Roeper hadn't attended the Million Maga March in DC on November 15, 2020 but other NC Oath Keepers did and based on what they saw there, the NC Oath Keepers decided to splinter off from the national OK group.
My aside: This splintering happened quite bit from 2014 on. The group was too big and unruly, and the leader/founder was a narcissistic blowhard who loved giving out orders from the comfort of his couch/bunker/computer screen while constantly hitting up OK member for donations.
Roeper was armed that day. As a retired fed, he was LEOSA certified so he was legally permitted to carry in DC.
My aside: methinks there should be a requirement that such certification turns off if you join an extremist group.
That's some imaginative excuse right there 😂😂
Just sayin'.
