Excerpts from CBSChicago:

Police and fire departments prepare for the worst: mass shootings, terrorism … at the Techny Towers in Northbrook. Three case studies: terrorism in Mumbai, India; the mass shooting at the movie theater in Colorado, and the Boston Marathon bombing are all shaping a homeland security exercise in Northbrook.

Multiple communities learned what Winnetka Police Chief Pat Kreis calls a new model for emergency response. In the old model, Kreis says, “Often times before this training we would focus on the police officers moving each patient out to a location to transfer to the paramedics.” Now, the police officers and paramedics are trained to go in together, officers securing the building while paramedics in bullet proof gear begin treatment right there, even in a gunfight.

The American Medical Association reports people at the 2013 Boston Marathon are alive today because they were first treated at the scene. Before they saw a hospital emergency room. “The Boston Marathon bombing was a great example of how many lives are saved because of how quickly those wounded persons were moved into the EMS system,” Kreis said.
