That was just a 30 year old guesstimate , I reached out to a guy that should know the CPD story but very possible, the D series may have a lot more beyond CPD.

Don't pass up Gene & Judes, still there but so many of the " memorable" places have changed or moved on.

The area has done a 180 compared to pre millennial times.
BigDaddy7972 was spot on and yes the response time could be 3 to 5 tomes longer than you would remember, primary reason is that district went from pron 350+ coppers to maybe less than 200 not including O'Hare.
I will say this though, those there now do try their best to do what has to be done with what they have. I was very skeptical 10 years ago when I saw the manpower drain but have seen what I consider a valiant effort under those circumstances.
Tact teams exist but from what I understand. they report to the westside daily and rarely seen at night.
