Chicago first responders hold emergency scenario drill downtown
CHICAGO (CBS) -- Police and first responders were on the Chicago River downtown on Wednesday, but it was just a just a drill.
The Chicago police and fire departments took part – along with a host of other agencies.
They tested their preparedness for multiple emergency scenarios – some on land, others on water.
The exercise was part of the National Homeland Security Conference, which is taking place in Chicago for the first time.
The Fire Department said the dive rescue and hostage demonstrations in particular, were a "huge success."
