I have been told that, at least in my area, the trigger for the light sensor is in the middle of the lane 3-5 feet back from the crosswalk lines. Usually under the large arrow, if there is one there. But I really agree with the four way stop idea. I would much rather get a ticket than have a run in with the assailant.

Now, I may sound like a crazy person here, but I swear I am not. I have carried Mace a few times, but I always have felt safer carrying a knife. You can find smaller ones that you can tuck into your sock or sleeve that will still pack quite a punch.

I really hope that guy is caught and you don't have to worry anymore.
