Legacy news has revealed that "the local tactical team" was using the 2-story building just behind and Fox News just revealed the following:

"The shot that killed the man who attempted to assassinate former President Trump at a rally in Butler, Pennsylvania, last Saturday was a "one-in-a-million shot," according to a source familiar with the investigation into the shooting.

Fox News learned from the source the kill shot was a single shot taken by a Secret Service counter sniper whose view was obscured.

A local tactical team also took a shot at the would-be assassin, 20-year-old Thomas Matthew Crooks, but missed."
