I remember one time making a left turn in a 2-lane pocket. A crown Vic went SCREAMING past me, no lights/sirens, I nearly pissed my seat
Since I grew up with several of the brass I placed a call. Told them the time/date and the chief called me back and said they were responding code (?) to an armed robbery in progress and didn't want the perps to know they were coming
Ok, but we were 10 blocks from the scene, he could have flashed lights/blipped horn
