President-elect Donald Trump's tweets often trigger what is now commonly referred to as Trump Derangement Syndrome.
You've seen the symptoms: the wailing and shrieking of tortured liberals; references to Hitler and the end of days or whatever dark prophecies can be tweeted with two left thumbs.
But there was an intriguing Trump tweet aimed at Chicago the other day — the dysfunctional Democratic machine town that gave political birth to President Obama and Mayor Rahm Emanuel.
Oddly, this Trump tweet didn't set off charges of fake news or hair pulling and screaming.
"Chicago murder rate is record setting — 4,331 shooting victims with 762 murders in 2016," Trump tweeted on Monday after a "60 Minutes" piece on the city's homicide epidemic. "If Mayor can't do it he must ask for Federal help!"
Trump is wrong on a couple of counts. Chicago's tally of 762 homicides isn't a record. Higher numbers were routine in the 1990s. But with more than 4,000 people hit by bullets last year, there is an argument that the city that used to work is more violent than ever.
Trump's talk of federalizing street crime, increasing the size of the leviathan, doesn't sound remotely conservative. It's something a big-government Democrat would say. Historically, many Chicago bosses have preferred the FBI worried about gun cases rather than public corruption.
Still, why so few, if any, shrieking lamentations when Trump let fly his tweet about Chicago homicides?
