Not going to happen. First of all Law Enforcement has to have a reason to "shoot" down a drone just like with everything else they do, not just seeing it flying. And secondly, it would be very stupid for law enforcement to start shooting drones since it would mean shooting in the air and what goes up must come down! which means it can cause bodily injuries to bystanders that might be around and that is a liability that I think very few or any officer is going to want to have... you shoot a drone and a stray bullet hits a kid 4 blocks away, yeah that will look real good on the city, department etc etc... and of course the drone itself coming down as well, it can crash and cause damage to someone's property or hurt somebody too... too many liabilities, so I don't see it happening
