Use of a firearm in the line of duty?

Little background is probably in order, but I am still fairly shaken up. Last night on patrol at 7PM we go a call from the adjacent county of a high speed pursuit entering our jurisdiction with suspected drug ties and confirmed presence of firearms. As I was the closest unit in the area, I followed textbook procedure when responding to the call.

We set up a spike strip along the 2 lane highway, as we got word the vehicle was traveling northbound at a high rate of speed, at times exceeding 100 MPH. We set up the road block with weapons drawn when the perps hit the strip and their vehicle hit an embankment, flipped on its side and came to a rest aprox. 300 meters west of our position. As we approached, we witnessed 2 perpetrators exiting the vehicle in a crawl with weapons in their hands. Myself, and three other officers loudly exclaimed "Put it down"!, and "Put the weapons down"!

I have drawn my weapon tons of times in the line of duty, but never fired. When supposed driver raised his elbow in an apparent effort to point the weapon in our direction, we opened fire. Both perps survived, but with multiple gunshot wounds. As it turns out, the suspects were fleeing a reported carjacking after robbing a connivence store at gunpoint earlier in the day. Naturally, IA is going to want to chat with me Monday, and I did not get back from the station house til almost 8AM this morning.

Was I in the right?
