They were at the south Bronx rally when i was there...buzzed overhead the entire time from 2 hours prior
My local PD used drones at the local 4th of July event and has for several years now.
Drones are incredibly cheap. Why was not all surveilled with drones? The close areas should have had agents on the buildings especially the one most close to Trump of which the assassin tried to kill him. What happened is total incompetence or it was worse I pray it wasn’t something worse.
