Thanks for a very good posting of the insight from a LEO! He wrote the item very clearly and without any bias.
This little aside caught my eye: “...I am from Oak Cliff.”
Grew up in Oak Cliff (the oc in my user name) and fully understand his reference to street fighting! Was common behavior in the ‘40s-’50s when I was a kid, but was mostly whites on whites. ....I’m guessing the LEO grew up there in later years when after it became majority black/hispanic.
Just an FYI - the detective who wrote the piece is a she/her/female. There’s a photo at the link.
