The seminar was called “The Bulletproof Warrior,” and the instructors urged the law enforcement officers in the hotel conference room to make the decision to shoot if they ever feel their lives are threatened.

Videos of bloody shootouts between police and civilians emphasized a key point: Hesitation can kill you.

In the audience at the May 2014 seminar was a young St. Anthony police officer, Jeronimo Yanez, city records show. He’s now known around the world as the officer who killed Philando Castile minutes after making a traffic stop in Falcon Heights last week. (source)

Officer Yanez had been a regular attendee of “officer survival” courses that had militaristic leanings.

According to this article, Glennon was a co-instructor of the course that Yanez attended. A non-police officer named William Czech who attended the same course says he was horrified at the content.

He said he expected to see a presentation about understanding both how to avoid using deadly force as well as how to realize when it’s unavoidable. Czech said the course consistently emphasized the risk of hesitation.

A copy of the seminar booklet that he made shows a page titled “Thou Shalt Not Kill?” It cites Bible verses that emphasize prohibitions on murder, not all killing.

On the second day, the group watched the shootout videos. One is the particularly gruesome dashcam video of Andrew Brannan pulling over in his white truck in Georgia in 1998 and then shooting Deputy Kyle Dinkheller to death.

Czech said Glennon ran that part of the seminar.

“Every time a video came up where the officer hesitated, he would stop and he would say ‘This is a point where there should have been a reaction, he should have engaged,’ ” Czech said. (source)

Glennon downplayed Czech’s assessment, saying he just doesn’t understand.

He called Czech’s interpretation of the seminar “totally inaccurate.”

“That’s why we don’t let the press in,” Glennon said.

…The Bible verses are part of a discussion about officers dealing with guilt following a shooting, he said. (source)
