Secret Service Director Rowe, why was Thomas Crooks walking around unabated?

SS Director Rowe, why was Thomas Crooks walking around unabated? #secretservice #thomascrooks #trump For at least an hour before the shooting, Crooks was seen walking around near the rally area. Crooks was seen in video obtained by Pittsburgh ABC affiliate WTAE pacing just beyond the boundaries of the Trump rally at 5:06 p.m., around one hour and five minutes before shots were first fired. He was also seen walking around near the magnetometers minutes before the shooting, according to law enforcement sources. Some witnesses reported him as a suspicious person, law enforcement sources said. He then made his way to a nearby building, climbing up air conditioner units until he was able to get on the roof of an adjacent building, according to sources. From there, he moved onto a taller building next to it. Just before Crooks opened fire, rallygoers spotted him on the roof and tried to alert the Secret Service. In an unclassified briefing Wednesday, law enforcement officials said 20 minutes passed between when Secret Service snipers first spotted Crooks on the roof and when he opened fire on Trump. He was identified as a person of interest 62 minutes before the shooting, they said. (ABC News)
