I don’t believe anything sent the assassine to Butler Pennsylvania, other than the drumbeat in the media 24/7/365 of the hateful, incendiary extreme TDS vitriol against Trump supplied by leading Democrats for eight years running. They spoke and he believed in their vitriol and he acted on that.
Right, the level of incompetence by the Secret Service was just a mere coincidence:
1) They knew about Crooks for 57 minutes and still let Trump take the stage and be exposed
2) They secured the building Crooks took a ladder out in the open for part of the crowd to see but didn't secure the roof with silly excuses being the roof of sloped or it was too hot to have someone on it.
3) They let Crooks fly a drown over the area almost two hours before the event started.
4) Somehow the body cameras of the Secret Service members there were turned off.
5) A counter sniper doesn't take a shot at Crooks until after he got off eight shots.
These are not believable examples of incompetence. They are far more likely examples of complicity.
And, it's incredibly naïve to think a regime that has tried to imprison Trump for two years wouldn't allow an assassin to take shots at him.
