Lots of good information in here:

By 2016, Chicago's murder
clearance rate had dropped to only 21%, and its
detective force had dwindled from 1,151 in 2009 to 863 as of July 2016.
[43][44] Warmer months have significantly higher murder rates, and over 70% of murders take place between 7 pm and 5 am.
[45][46]
In 2011, 83% of murders involved a firearm, and 6.4% were the result of a stabbing. 10% of murders in 2011 were the result of an armed robbery and at least 60% were gang or gang narcotics altercations. Over 40% of victims and 60% of offenders were between the ages of 17 and 25. 90.1% of victims were male. 75.3% of victims and 70.5% of offenders were African American, 18.9% were Hispanic (20.3% of offenders), and whites were 5.6% of victims (3.5% of offenders).

Murder rates in Chicago vary greatly depending on the neighborhood in question. Many of the predominantly African American neighborhoods on the
South Side are impoverished, lack educational resources and noted for high levels of street
gang activity.
[47] The neighborhoods of
Englewood on the South Side, and
Austin on the West side, for example, have homicide rates that are ten times higher than other parts of the city.

OK, I understand your argument. You have a point. Are you saying you don’t think deterrence plays a role at all?
Re the National Guard, I don’t know for how long. Years. Until the cycle is broken. Probably only need them for the summers, though.
