Chicago Police are kicking off an experiment in a neighborhood on the city's West Side, hoping to alert would-be criminals that they're being watched and face stiff penalties if they're convicted of crimes.
The Chicago Sun-Times reports a commander is set to begin knocking on doors Friday to deliver warning letters to about 20 people who statisticians say are most likely to become shooters or crime victims.
The "custom notification" letters come after police identified more than 400 "hot people" across the city who are most likely to be involved in often-fatal shootings.
Right now the targeted effort is limited to a single district in the Austin neighborhood. But police hope to expand the practice as gang violence continues to make headlines.
