Anything with lights and a siren is now a target. I had a boss in South Central LA who told me about the time she heard something hit the side of the ambulance on the way to pick someone up at the hospital (no lights, no siren, just a grunt call), when she got out she found a bullet hole 2 inches behind where her head had been. Those people don't care what happens until it's them in the back. Usually if it was a gang related call like this we tried to get going as fast as possible just in case they came back with a bigger gun the next time. The police presence helped but didn't always deter them. I got some good advice once, when they start shooting jump behind the fire truck, they stop bullets really well.
