I was driving home from school, and got a weak Ka alert. The problem was, I seen a leo coming towards me for a good 20 seconds. My detector didn't alert until he was about 30 feet in front of me. I was thinking wow, I just received my V1 about a month ago, and this is happening. As I passed him, the arrow was still pointing forward. At this point, I'm really thinking wow, this isn't good at all. Come to find out, the alert was coming from another leo with his car parked about 1/2 of a mile down the road. I was obviously thinking my Valentine had already really screwed up on me, but thankfully, that wasn't the case. This has happened to me before, so I shouldn't have jumped to a conclusion, but I couldn't help but to worry about it at first.
