I was thinking about what happened in Chicago and the character that tried to attack Trump on stage. They are re-evaluating their security going forward. They do not want to put the rally goers at risk and of course Trump. I would imagine that they would carefully select the rally locations and the type of security needed both inside and out of the arena.
With what happened in Chicago, the national guard needs to standby. It took close to 2 hours for all of the rally goers to leave the area because of the disruptors. Inside the arena there were more than the usual number of disruptors and they were getting in peoples faces. I would imagine that inside security would also have to be significantly increased.
I heard the E mayor and captain of police actually cut the security in Chicago that’s when the officers went to USSS
