Same here. I just took some yesterday of a building and a car on fire here in town. I stayed out of the way and they didn't say anything to me. I have taken tons of photos of crime scenes, fatalities, fires, wrecks, Etc. and they never really say anything as long as I stay out of their way.

Usually the only time they ask you to leave the area is when you may be in danger or a minor is involved.
