Drones In the Sky to Stop Assassinations and Mass Killings

I heard someone on the radio suggest we use drones to prevent shootings such as the one in which Charlie Kirk was killed. The drone would fly above the site of the event, searching for anyone who might be crawling atop the buildings or carrying a gun. The drone would also look for those who might be visible in the windows of high buildings, scanning for those carrying weapons. It would also pick out those at ground level who were carrying guns.
 
Considering the mass murders and assassinations we have had that could be prevented, such drones seem a must.  

Democrats Stepped Forward to Condemn Charlie Kirk Shooting

Let's make a list of the Democrats we know of who condemned the shooting of Charlie Kirk: Joe Biden, Kamala Harris, Tim Walz, Bill Clinton, Hilary Clinton, Barack Obama, Michelle Obama, Tammy Duckworth, Elizabeth Warren, Cory Booker, Chuck Schumer, Amy Klobuchar, Nancy Pelosi, Hakeem Jeffries, Adam Schiff, Maxwell Frost, Eugene Vindman, and Mark Kelly.

And there probably are others, probably are more. We thank these leaders for stepping forth to condemn the killing of someone from the opposite side of the aisle. No decent person wants political assassinations.
