Accident on I-10 west just before ramp to 410 west

About 11:40pm as I was driving home, I saw an SAPD officer slam their car into the back of a vehicle that was already in the process of being pulled over by another officer. Smoke, glass, and car parts were all over the right 3 lanes just before the ramp up to get onto 410. I wonder how they are going to explain that...
