I think it depends. In the city I'm in, jaywalking is a pretty accepted norm. I always look both ways and if there's no cars coming, then I'm not going to wait for the signal to change to tell me I can walk, especially in some intersections where it takes the signals forever to change. I'll just cross, although I'm not the type of person who will cross in front of a car and expect the car to stop for me. I also tend to cross in crosswalks, although every now and again I won't (depends on how busy the street is). My roommate is from the midwest, though, and always freaks out when we jaywalk - it really just depends on the norms of the city/geographic area you're from, I guess. I mean, I've jaywalked plenty of times in front of cops and have never once been stopped, nor have I heard of anyone else being stopped, either.
