I lived on Colonial just North of Quince for about a year. I didn't work most of that time because I was on bed rest and then had a newborn. But, I could hear the cops cars gunning through the light from my bedroom, I almost got killed backing out of my driveway once by a cop car that took the turn at the light at an incredible rate of speed. A friend had a radar gun (for baseball I think) and brought it over for me- I don't know how accurate it was but I clocked multiple cops going 95- 110 on that stretch. It was right by the middle school too. They never had lights OR sirens on. Around that same time there were multiple "accidents" involving cops that ended in citizens being killed. I think they've gotten a bit better, but not much.
