For purposes of this discussion, it doesn’t even matter where you attribute blame. You can try to claim that this 99.9% white crowd was 100% BLM supporters for all I care.
I only offer the photos for the purpose of reminding everyone there was a major security breach at the Capitol lately that explains the fence.
Compare and contrast with the barricades Trump had erected at the White House when that complex has never once been breached, etc.
