This. There's probably more tools that detects all kind of drones other than DJI's with DJI Aeroscope, but law enforcement surely has them.
I'm a bit perplexed how we have those drone incidents at major airports like Glasgow and they can't find the drone operator. Unless they are flying home built ones. But I believe all big brands like DJI transit their position as well as the controller position on the ground (so law enforcement can get to you within minutes if they use the drone detection tool).
