I have a couple of drones (toy/training status models). My small one is smaller than that but with no camera.
In the UK the Police have been quick to utilise drones for rescue/missing people. They are also using thermo imaging to loacate grow houses (as are the thieves) and to secure evidence for convictions.
Probably better using a scanner (if they still work) to locate the police and then send your battery time limited drone up to watch them.
