The cops are another bunch who have been looking at drones used in Ukraine and are getting ideas of their own. Think about it, a surveillance multirotor drone that can stay up for 40 minutes now, in the not-too-distant future could have batteries that last 5x longer 200 minutes, or 3 and a half hours! It would also have some serious range all over the city using the 5G cell network with high data rates bigger ones could use starlink for some serious data rates and multiple 4K cameras with all the bells and whistles and be "crew served" with pilot and multiple observers each with their own monitor! At the triangulation of a gunshot sound, it could be on the scene in minutes. So now you have a drone that can move around it's assigned area of the city at 40 or 50 MPH and stay aloft for over 3 and half hours, now we are talking something seriously useful. You will most likely see such batteries in drones early, produced by pilot plants for automakers to test them and other uses like cellphones, computers and drones.
Here's another idea, an FPV drone that pops out of a box on the roof of a 7-11 and hunts down robbers in the parking lot with a taser and mace spray with dye! All controlled by a cop in the office, AI identifies the targets, fires up the drone and flies it to the aiming point then he presses the button!
Welcome to the future!
