Tactics, Techniques and Procedures are constantly improving in the realm of small unit emergency response. In the interest of improving TZ Critical Incident Response TZRD has conducted a After Action Review (AAR) of the Critical Incident Response(CIR)conducted by Dallas Police & DART Police.This intelligence product was compiled with information drawn from multiple sources including CBS News.

From CBS News: 8:57 p.m. – First shots fired

By 8:57 p.m., many of the demonstrators were headed back to their vehicles when the eruption of gunshots rang out.

“It came out of nowhere,” demonstrator Corey Hughes said that night, “As a matter fact we were towards the end of the protest when the shots started firing off. I’m kind of startled and shaken up.”

Moments earlier Micah Johnson parked his black SUV on Lamar Street in front of El Centro College.

With his hazard lights flashing, Johnson stepped out and put on a body armor vest. He was armed with a semi-automatic assault rifle along with a handgun.

Johnson then moved south on Lamar Street towards Main Street where officers had gathered to block traffic for the protesters.

Johnson then opened fire.

The sound reverberated off the buildings causing confusion as to where the shots were coming from.

Dallas Police Officer Michael Krol, Senior Cpl. Lorne Ahrens, and Officer Patrick Zamarripa were killed in the initial gunfire.

9:01 p.m. - A call for help

Shortly after 9:00 p.m. officers radioed for backup.

Officers physically carried their shot colleagues as they loaded them in the back of squad cars and rushed them off to the hospital.

Meanwhile, Johnson headed north on Lamar Street firing toward DART officers who were coming from the West End Station to the scene.

DART Officer Misty McBride was shot while running to take cover behind a car. DART Officer Lee Cannon and Dallas Police Sgt. Giovanni Wells were also hit. (Wells requested his picture not be published)

El Centro College officers initially keep gunman out

At this point, Johnson tried to enter El Centro College by shooting out the glass doors on Lamar Street, but El Centro College officers Brian Shaw and John Abbott were inside blocking Johnson from entering.

Both officers were wounded by gunfire but they forced Johnson to move on.

Video captures gunman killing DART officer

Johnson then headed down Lamar hiding behind concrete pillars before sneaking up on DART Officer Brent Thompson.

Video from a nearby rooftop shows Johnson firing to the left of a pillar Thompson was using as cover and then going around to the right shooting Thompson in the back.

Then standing over him, the video shows Johnson shooting the DART officer again and again.

Gunman enters El Centro College

Johnson then turned the corner and went down Elm Street.

This time he was able to enter El Centro College. Johnson went up the stairs to the second floor, through the library and down a hall.

There from a window looking down on Elm Street, he once again opened fire.

Dallas Police Sgt. Michael Smith who was by the 7-Eleven on Elm Street was shot and killed.

DART Officer Jesus Retana was shot in the arm.

9:15 p.m. – Standoff inside El Centro

At 9:15, Johnson made his way down a long hall in El Centro College where officers cornered him.

Thirty feet separated SWAT officers from Johnson.

For the next several hours, officers tried negotiating with the gunman.

Dallas Police Chief David Brown said, “The suspect said he was upset at white people. The suspect said he wanted to kill white people, especially white officers.”

Negotiations eventually broke down and more than 200 shots were exchanged.

1:28 a.m. (July 8) – Bomb kills gunman

At 1:28 a.m., Brown made an historic decision – something no police department had ever done before.

Brown ordered a bomb robot with C4 explosives to be sent down the hallway and when it was just feet from Johnson the C4 detonated.

Four-and-a-half hours after the first shots were fired Johnson was dead.

UAV SAR missions do not easily fit into a ready-made template. They are as diverse as the SAR exercises and organizations they support -- ranging from quick response in confined hazardous environments to persistent observation of large areas over long periods of time.
