A few loyal volunteers with drones and radios is inexpensive security
I was thinking the same thing - volunteers at each venue coordinating with local law enforcement.
Didn't the Proud Boys used to provide security for Ann Coulter and Tucker? That could be our model on a local level but whoever said here that colleges will demand extra security now, especially for conservative speakers, is correct.
I remember seeing clips of Ann Coulter at events with one or two bodyguards in a room full of demented students...
That was years ago, times have changed for the worse.
