Three activists have been found not guilty on the most serious charges concerning an alleged terror plot against Chicago’s 2012 NATO summit. Brian Jacob Church, Brent Betterly and Jared Chase — known as the NATO 3 — were arrested after undercover police helped them make Molotov cocktails. They faced up to 175 years in prison under a post-9/11 anti-terrorism law invoked for the first time in their case. On Friday, a jury rejected the charges of providing material support for terrorism and conspiracy to commit terrorism. The three were instead convicted of misdemeanor mob action and felony possession of an incendiary device. Supporters say police entrapped the NATO 3 and prosecutors brought excessive charges to justify the summit’s high security costs.
