The city of Chicago is buying an additional 8,500 face shields for its police officers as the city continues to prepare for the NATO conference.
The shields, which will cost the city about $757,650, will fit over police helmets and provide added protection against rocks or fluids.
The additional purchase from Colorado-based Super Seer Corp. brings to 11,570 face shields that are twice as thick as the old ones, with a larger surface and air-tight seal.
Chicago Police Department spokeswoman Melissa Stratton would not say how many officers are expected to use the new shields during the summit, which is scheduled for May 20-21. However, she said department officials decided to upgrade all its shields with an eye toward the long term safety of officers.
