They look scared, because they are
This was a very telling insight from a reader at electoral-vote.com.
Minneapolis Is Apparently the Hill that The White House Wants to Die On, Part VI:
The horrible killing of Alex Pretti brings to mind something I observed when dating two different men.
One was raised in the suburbs, no fighting allowed, only playdates, no roaming around the neighborhood, etc. The other was raised in a very gritty blue-collar town where there was a lot of fighting in the streets, every day, with kids of different ethnicities. Not just Black vs. white, though that did exist, but also various other ethnic groups fighting each other. He learned the hard way to defend himself while walking home, starting at the age of six.
Went with boyfriend one to a rock concert that took place in a college gym. I'm a very small woman and we were in the bleachers and some energetic attendees knocked me off; I almost fell through the seats to the floor below. Boyfriend one reacted as if it was World War III—very aggressive, ready to fight everyone. He panicked.
Went with boyfriend two to a football game where we were rooting for the "wrong" team and the blue-collar guys in the stands were passing flasks (before the days of screening at the entrances) and were very displeased at some people in our party who were enjoying seeing our team winning. They started pushing us, and again I was in danger of falling. Boyfriend two stood up, put on his Jack Smith face, and said that we were leaving. We were allowed to leave without a problem. He was used to fighting and they could tell.
Of course, I married boyfriend two. We had sons. We made them take a martial arts course in school so that they would know how to handle both pain and anger when encountering others. It has served them well.
The ICE guys look like they bathed in video games instead of getting out there and learning any sort of martial arts. They look scared, because they are.
