1) Chicago isn't discussed for the same reason not every murder in every other big city isn't discussed....they're not covered.  An event that spikes a city's murder rate is going to get more attention.  2) If Chicago is a mess because of failed liberal policies, then how is it that a city like Toronto has 3.5 million people, tighter gun laws, and is just as liberal, has a fraction of the murder rate as Houston, let alone Chicago?  Seems to me that either gun laws might do some good, or Americans are effed in the head.  Toronto had 73 murders in 2016, which was high for them (usually in the 50s....and the number of murders is down 41% so far in 2017).  Houston had 323.  3) Toronto is a city that is about 50-50 white/visible minority, so that blows your "racist" argument out of the water.

So, how is it that a country with tighter gun laws, and generally is more liberal (single payer, legal same-sex marriage long before the US), has a much lower murder rate than the US?
