This assassination attempt was almost definitely a false flag.

Let’s, for sake of argument, say it wasn’t.

The location has plenty of security, security that successfully stopped the gunman.

In what world would this mean “obviously we need more security.” The security worked, it has enough funding, also the thing that protects the president is the secret service which is part of the department of the treasury, not DHS.

So the secret service did their job and stopped a threat and for some reason that means we should give an unrelated part of the government more money.
