A Facebook argument had apparently sparked a completely unrelated shooting at the start of the weekend. Best friends Jordan Means, 16, and Anthony Bankhead, 18, got into the online spat with a man in his 30s. The man is said to have followed his final post by appearing in the flesh and shooting the two teens to death.

Two other men were fatally shot later in the weekend as they sat in a car that was also occupied by two kids, ages 3 and 7. The children were physically unharmed but no doubt will join those who are as mentally scarred by living in Chicago as were some combat veterans who returned from the war in Iraq.

And this bloody Easter weekend was preceded by a weekend in which 37 people were shot, four of them fatally. FBI Director James Comey happened to be in Chicago the following Monday, and he ascribed much of the violence to the gang culture so deeply ingrained in the city. But Comey had little to say about what Chicago Police Superintendent Garry McCarthy recognizes as the core problem.

“Until we do something about guns, don’t expect things to change overnight,” McCarthy said at a press conference that same day.
