Police shootings have been triggers for much of the current violence. However, most of us have understood that - regretfully - an armed police force does occasionally kill someone under ambiguous circumstances.
Now we’re starting to see civilians shooting each other, in Kenosha and Portland. This doesn’t end well, it can escalate into the sort of bushwhacking Missouri was plagued by in the 1860s.
Those who’ve viewed what’s going on as the precursor to a civil war begin to look less alarmist and at least somewhat prophetic. It grows clear there are significant numbers on each side who would celebrate the death of members of the other side.
While history is said not to repeat itself, it often rhymes. Grandma Pelosi, aka "Lady Botox," has already declared President Trump and the Congressional Republicans to be traitors.
The reelection of Donald Trump could throw down a gauntlet the other side cannot shrug off; the sort of casus belli the election of Abraham Lincoln proved to be to the South. There is certainly precedent aplenty in our history and others.
