Narrative:

I arrived at the scene of the police station. I checked my flight apps and saw that there was no tfr and so I started filming. In my mind I thought that I was clear as the rioting occurred at night and so I suspected that if another tfr was going to be put in place it wouldn't be enacted until later that day.I already had the laanc grid clearances for the airspace for drone flight. I had secured these the previous evening.I consulted with the police and national guard that were at the location and they said they were fine with me filming.my goal was to document some of the destruction that had occurred the previous evening.there were several fires actively burning; lots of soldiers and police moving around; loud speakers blaring - it was not a calm environment. I was focused on flying safely and filming.I pretty much filmed a building or location and then hurried to the next one. There was a lot of stuff happening and I was very busy trying to capture it.although I did check for a tfr when I arrived; I did not check for one at each location that I filmed. Often I was moving one or two blocks and then taking off again with the drone; often without even turning the drone off and then on again.I finished filming [about 3 hours later]. It was at this point when I had a chance to sit down that I looked at my aviation app and noticed that a tfr for the area had gone up [several hours earlier].I had an officer with me - at no time where we anywhere near other manned aircraft. There were a few helicopters in the air but we stayed well clear of them. I often go to a location and start filming. I always check for tfr's at the beginning; but the lesson from this I think is that in a tense situation I will check more frequently.
