I found this article in the archives of the New York Times. Dated April 6, 1889, it shares the story of some Iowa squatters who, in defending what they defined as their land, fired upon U.S. Marshalls. Makes me wonder if we will be seeing more of the same as more homes are foreclosed upon and people, fed up with the (utterly dysfunctional and archaic) particular belief system that dictates who gets to own land and who doesn't, will rise up and affirm: NO MORE.
That aside, it's an interesting read. Gotta love the journalistic style of the time.
