I love that the doggo didn't just let go of the rope after his rescue. "Yeah, that's mine now."

I strongly recommend you read The Code Breaker, by Walter Isaacson. It's about Jennifer Doudna's work in the field, and clearly describes the research and processes involved in the most layman of terms.

I think SOME departments screen. A smaller agency like the Hardin County Sheriff's Department may not. If it does, it clearly did not screen to determine how someone might react in situations like this.

There is absolutely no way a person experiencing what these cops did during the chase will not have a strong emotional response--it's inevitable. What is not inevitable is the way these cops responded to their emotions. Incidents like this make a strong case for pre-service psychological testing to determine if a person has the right mentality to serve as a cop. Trouble is, people with the right mentality probably don't want to be cops.

That hair looks like it's dialed up to 11.
