A friend of mine was one of LBJ's SS agents when LBJ was a vp and later when LBJ became potus after JFK was killed.
When not on watch, sometimes he and his peers made house calls on rectums like Beck. If the rectums gave them any wise guy attitude or lip, the house calls went to a more serious level. Then, the rectums found out how serious the judges took someone joking or making threats on a Potus.
The attempts on Ford and Reagan, have made the SS take any threat in a very serious manner. There is zero tolerance for any jokester threatening any potus or potus candidate.
Yes I have a feeling they sobered Beck up real quick. :-)
