In a dramatic development in the ongoing investigations into the failed assassination attempt targeting the US President at the White House Correspondents' Dinner, the District of Columbia Attorney General, Janine Ferries Perro, released a video documenting the critical moments preceding the shooting, highlighting new security and technical details.

Timeline Video: 5 Minutes of Monitoring

The clip, published early Friday, showed the movements of the suspected gunman, Cole Thomas Allen, more than 5 minutes before the attack began. The video highlighted important points:

• Prior Reconnaissance: Cameras spotted Allen inspecting the "Hilton" hotel area a full day before the attack, indicating premeditated and deliberate planning.

• Zero Hour: The video documented Allen firing at a US Secret Service officer while attempting to reach the President.

• Refuting Friendly Fire Hypothesis: Attorney General Perro unequivocally confirmed that "there is no evidence that the shooting was a result of friendly fire," in a direct response to the speculations that arose after the incident.

The Mystery of the Police Dog

One of the most striking scenes in the video was the behavior of a police dog belonging to the Secret Service; the video showed the dog exhibiting an unusual reaction and clear anxiety moments before the first shots were fired, raising questions about the ability of vital security systems to detect threats before they occur.

Who is Cole Thomas Allen? The "Surprising" Suspect File

• Distinguished Teacher: He worked as a part-time teacher at "C2 Education," and even earned the title of "Teacher of the Month" in December 2024.

• Video Games: He designed an independent game sold on the "Steam" platform, and was working on a second project titled "The First Law."

Motives and Affiliations

• Inventions: He was known in academic circles for developing a prototype emergency brake for wheelchairs, making his turn towards armed violence a shock to those around him.
