NATO came to Chicago in May 2012, and security officials just can't help themselves talking about how well it went off. 

Although 90 people were arrested and eight officers were injured, the Chicago Police handled the weekend's NATO Summit protests with decided restraint and strategy.

During a tumultuous weekend in Chicago, two groups of men have been charged with conspiracy to commit terrorism, mostly with Molotov cocktails. 

With the NATO Summit less than a week away in Chicago, additional security measures are springing into action.

Metra, a commuter train service, announced its plans to ramp up security for the NATO Summit, including closing 26 stations on Monday, May 21.
