We are being told that it was "a mistake" that the ideal location for a sniper to be located was left unguarded, and somehow Thomas Matthew Crooks was able to identify this oversight and position himself accordingly.  Just 150 yards away from where Donald Trump would be speaking, Crooks was able to climb on to a roof with a rifle and stay there for nearly half an hour before he finally started shooting at Trump.  Either this was a cataclysmic security failure, or Crooks had some help somewhere along the way.

According to a former Secret Service agent who was in charge of Vice President Al Gore's security detail during the Clinton administration, there should have been Secret Service personnel on that roof and "someone dropped the ball"…

Before a high-profile person like Trump attends an event and needs Secret Service protection, the agency conducts a security survey that also takes nearby buildings into account.

William Pickle, a former special agent in charge of the Secret Service's vice presidential protection division who oversaw Vice President Al Gore's detail, told USA Today that something was clearly missed. "We know who's there, why they're there, we have control over those buildings," Pickle said. "It seems like somewhere in this security survey, someone dropped the ball on those particular buildings."

Was this just a mistake, or was it done on purpose?

Former Secret Service agent Dan Bongino is claiming that an "unimpeachable source" has told him that someone was supposed to be on that roof but never showed up…

NEW: Dan Bongino says an "unimpeachable source" tells him that someone was supposed to be on the roof where Thomas Crooks shot from but "didn't show up."

Bongino also claimed that the Biden admin is telling the USSS director to keep her mouth shut if she wants to keep her job.

"According to my source, that roof was supposed to be a police post… [there] was so supposed to be someone there."
