Was coming home today 4 lane road and got a whiff of ka. I always speed on this road about 15-20 over. Couple seconds go by and got another. Then another. Kept looking around and noticed a blacked out unmarked suv about 1/4 mile back in traffic. He was sampling oncoming traffic with I/o ka. Next thing I know he pulls a U and goes after someone in oncoming lanes. R3 knew he was there the whole time!
