Devastating Witness Videos Reveal Exactly What Happened In The Dallas Shooting

Horrifying videos are appearing online as details continue to emerge about the Dallas shooting Thursday night.

Twelve officers and two civilians were shot, according to Mayor Mike Rawlings. The death toll remains at five law enforcement officers. One suspect was killed by police.

The most shocking video to surface so far appears to show the moment an officer was shot dead at point-blank range.

WARNING: The following footage is distressing.

One eye witness claims one of the shooters told him "someone's going to die tonight" before he cocked the rifle and the carnage unfolded.

This video shows the moment the rally turned into a stampede when shots were fired around 8:45 pm on Thursday.

Hundreds of people had gathered to protest the fatal police shootings in Baton Rouge, Louisiana, and St. Paul, Minnesota.

Meanwhile, the horror was caught on camera from another angle. A Twitter user posted a clip showing an exchange of gunfire with the caption, "I am so scared."

One witness shared a video appearing to show a protester getting arrested.

Michael Bautista caught this dramatic scene while hiding behind a tree. It shows an exchange of gunfire and Nasheed said he could see an "officer down."

Texas Governor Greg Abbott issued this statement on Twitter.

And from Warsaw, President Barack Obama branded the tragedy “a vicious, calculated and despicable attack on law enforcement.” He added nothing can justify such acts of violence and that “justice will be done.”

Statistics from the National Law Enforcement Officers Memorial Fund show this to be the deadliest incident for US law enforcement since the 9/11 terror attacks. DART officer Brent Thompson, 43, is the first victim to be identified.

A Dallas Police Department spokesman said, "Our hearts are broken."

Three suspects are in custody. Downtown Dallas was still declared an active crime scene as of Friday morning.
