This happened in Chicago on Friday:

Police in Chicago arrested a man wearing body armor and carrying a loaded gun at the city's Union Station on Friday. The Cook County state attorney's office told Chicago ABC station WLS that Isaiah Malailua, a native of California, was charged with unlawful use of a weapon/body armor. Malailua, 21, was allegedly carrying a loaded 9 mm pistol, wearing a bulletproof vest and had a duffel bag filled with SWAT equipment, WLS reported.

And this happened in Sacramento last Sunday:

Sacramento police officers shot and killed a black man in his grandmother's backyard because they believed he was pointing a gun at them, police said. But investigators say they did not find a weapon at the scene, only a cellphone near the man's body. The fatal shooting of Stephon Clark on Sunday night was recorded by two officers' body cameras...

Malailua, armed and walking through a crowded public place dressed like a wannabe mass shooter, was arrested without being shot twenty times and is now in Cook County Jail. Clark, standing in his grandmother's backyard holding a cell phone, was shot twenty times and is now in a morgue awaiting autopsy.

One of the things we're told about trigger-happy cops—and one of the reasons some cops cite for supporting gun control—is that since our guns laws are so lax, they have to assume everyone has a gun and, you know, "react accordingly." But along comes an Isaiah Malailua, someone the cops know is armed, and they somehow manage to take him into custody without firing a shot. Dylan Roof, who was still armed when the cops caught him, was also taken alive—and then taken to Burger King.
