Maj. Terry Seilhamer told the Pittsburgh Post-Gazette troopers earmarked for the Sept. 24-25 summit were already undergoing refresher training on crowd-control tactics in the event demonstrations get out of hand.
The state contingent will also include specialists such as dog handlers, helicopter crews, bomb technicians and SWAT personnel.
The G20 Summit will include finance ministers and central bankers from 19 nations and the European Union.
The Post-Gazette said Wednesday the city has been working on myriad details ranging from food to housing to workman's compensation insurance related to the deployment of some 4,000 officers from the city, state and surrounding communities.
