That’s awful. That makes it seem worse to me. Seems like a situation you would want to approach with a lot of trained personnel, backup, and a gentler approach. Not aggression or Dirty Harry style justice.
Just my opinion. I don’t know the details. I just like when situations can be dissolved rather than escalated. I was a bouncer when I was in college and I grew up in a house with a lot of violence. I prefer to take care of things reasonably whenever possible. This doesn’t seem like that kind of situation.
Thee just is no way to make “sense” of this with the information we have. It appears that not only did he shoot the boyfriend, he attempted to shoot his adopted daughter. His only plea has to be insanity.
