This is on point. I'm Megna Chakrabardi. For the US Secret Service, July 13th began as a routine campaign event.

Agents arrived in Butler, Pennsylvania three days before Donald Trump's rally,

and met with local law enforcement to develop the advanced security plan.

That plan included establishing the so-called protective perimeter around the Secret Services

Protectee.

The AGR building sat about 400 feet from the stage. It was outside the protective perimeter. On July 13th a

gunman climbed to the rooftop and attempted to assassinate former President

Trump. He killed one person and gravely wounded others.

I went to the roof of the AGR building where the assailant fired shots and I lay it in a

prone position to evaluate his line of sight.

What I saw made me ashamed.

As a career law enforcement officer and a 25 year veteran with the Secret Service,

I cannot defend why that roof was not better secured.

That is acting director of the Secret Service Ronald Rowe.

The Secret Service did not hold a public press conference about the event for quite some time.

Former director, Kimberly Cheetel, was forced to resign on July 23rd, and Roe, who has been with the Secret Service since 1999, stepped in.

And on August 2nd, he laid out a timeline of events that took place on July 13th.

Rose says the security team did customary final sweeps that morning and then opened the protective

space to the public at one o'clock in the afternoon

hours before Donald Trump arrived.

According to reporting by the New York Times, at about 426 p.m. a member of the local Butler County Counter sniper team

texted his colleagues about a suspicious individual outside the fenced area of the Butler Fair Show grounds.
