I noticed the difference in this show as well, and I hope it continues.
Besides any conscious philosophy of the producers & writers, perhaps making the show more character driven as opposed to procedural has an impact on the stories. Maybe it's easier to understand when a suspect's rights are being violated (and to not be banal about it) when you're writing a deeper portrayal of the person who wields the power.
I always wanted to see a "pop up video" take on a cop show, where they have expository information and trivia from actual legal experts.
"Officer Jones just blew the entire chain of custody around the bloody knife"
"Flabbodell vs Borkweather says they have to give you access to counsel within X hours and they just ran out the clock"
"This type of traffic stop is explicitly forbidden in 17 states, including the one this show is nominally set in"
