According to one whistleblower, the night before the rally, U.S. Secret Service repeatedly denied offers from a local law enforcement partner to utilize drone technology to secure the rally. This means that the technology was both available to USSS and able to be deployed to secure the site. Secret Service said no.The whistleblower further alleges that after the shooting took place, USSS changed course and asked the local partner to deploy the drone technology to surveil the site in the aftermath of the attack.
