According to Breaking Points, text messages from local law enforcement show they were aware and tracking the shooter and knew he was carrying a rangefinder, up to 1.5hrs before he shot Trump.
Local police photographed the suspect and suggested notifying SS Snipers to "look out" and sending in someone to "check it out".
The Secret Service and those up in the chain of command appear to have ignored the warnings and their requests.

And now I'm wondering if they have any plans to defend against someone copying what drones do over trenches in Ukraine. Or are they waiting for it to happen first so that Congress has an excuse to restrict private drone ownership?
It was a DJI drone. The same type they already wanted to ban. The FBI helpfully told us they were able to "exploit" the drone to get flight information out of it after the fact.
It's worse than you think already.
Great point... a signal jammer would be the only obvious current solution. It's a problem in a war because it's like lighting a Christmas tree signals-wise, but for a political rally you're not worried about HARM missiles.
Shotguns are also an option. Or maybe an anti-drone drone.
