"Currently, an officer's job is to run toward gunfire, alone, with no support or Intel"

That's a lie, they don't run toward gunfire at all. And they'll wait until they have at least three departments of officers before doing anything.

If they want to break glass as a distraction they can do that already, they don't need a drone. And their plan to break glass will startle an already on edge and unstable shooter, instead of using tactics to de-esecalate the situation. Also, isn't this what swat is for? They have no qualms about flashbanging babies in cribs but when it comes to an actual situation all of a sudden they need drones so no cops are in any iota of danger.
