This sort of thing belongs confined to history:

Taylor writes that this investigation, which violated the civil rights of more than two dozen organizations in Wisconsin, may have been a political vendetta spurred by the wife of Milwaukee district attorney John Chisholm, the prosecutor behind this investigation.

A former prosecutor, described as “a longtime Chisholm subordinate,” says that Chisholm told him and others that his wife, a teacher’s-union steward at a local high school, was so upset over the union bill that Governor Walker sponsored and the legislature passed that she was “repeatedly moved to tears.” According to Taylor’s source, who refused to identify himself out of fear of retaliation, Chisholm said that “he felt that it was his personal duty to stop Walker from treating people like this.” The source, who professed to have admired Chisholm before this happened, stated that, “it was surprising how almost hyper-partisan he became . . . ”
