Chicago police Officer Aldo Brown shouldn't spend a single day behind bars for the 2012 recorded beating of a suspect at a South Side convenience store, his lawyer says. Instead, the veteran tactical officer should be commended for a career patrolling an area of the South Shore neighborhood so wracked by violence that it's known as 'Terror Town', according to attorney Daniel Herbert. "Aldo Brown doesn't go to an office each day, typing emails, participating in meetings or conference calls and thinking about the next run to Starbucks," Herbert said in a recent filing in federal court in which he seeks probation for Brown. "He starts each shift going into Terror Town, where he is ... the ONLY thing preventing already pervasive violence from completely overtaking the community." Federal prosecutors, though, insist that Brown is no hero. In asking for up to 2 1/2 years in prison, prosecutors said the burly officer committed a "violent and gratuitous beating," shown on surveillance video punching and kicking convenience store worker Jecque Howard.
