Can’t see sternly worded letters stopping Chicago’s war zone violence.

Via Politico:

Chicago police are going to hand deliver letters to people suspected of committing or being victims of gun crimes in an effort to stem violence in the city, according to a new report.

Starting Friday, a district commander will be delivering letters warning certain targets in that district not to commit violent crimes, the Chicago Sun-Times reports.

The pilot program is targeting individuals off a “heat list” developed by a Yale professor, who studied murders on Chicago’s West Side between 2005 and 2010 and found a small network of people was responsible for more than 70 percent of the killings, according to the Sun-Times.

The letters warn people who have been put on the list that they will be charged with the most serious crime possible if they are arrested for a violent offense.
