I would like to take a minute and explain some issues I have addressed with my agency. Its not a matter if another terriost attack will take place but when. I would like to raise awareness that secondary explosions targeting first responders of EMS and Police is a very real threat. Remeber scene saftey and I cannot press this enough. Do not get tunnel vision of treating this just like another call with victim's. Treat it as an active crime scene with the possibilty of secondary attacks. If you see something that dosnt sit right with you raise concern. Things such as trash bins out not on trash day, backpacks laying out, clump of trash in the gutter, suspicious heavily laiden cars, ext. Everyone stay safe out there and remember scene safety.
