Little fracas in the vicinity of Lexington, MA, and then in Concord, MA, as well. 1775 or thereabouts.
ZX12R ~ Waco slaughter, and the Oklahoma bombing as revenge for it. Both 19th.
While not disagreeing with an April 19 date, I think the big event will be later.
The Benghazi attack was timed to blur the focus on, to steal a little power from, to overwrite the big event a decade earlier.
Oklahoma City was to take back the date from Waco.
The most horrible date in human history (according to anyone invested in dominating others) is July 4th.
That's the day the real trouble starts.
