There's a certain amount of chicken and egg at work here. Yes, there are cyclists who run red lights and behave badly just because they can. On the other hand, there are traffic laws that I regularly break while biking to stay alive (crossing onto sidewalks, stopping in the road, even ignoring stop signs to get away from large vehicles). Having been hit by a bus while on the sidwalk, I'm acutely aware of how frail and unlike a car I really am.
In short, my choices aren't made based on traffic laws. They're based on trying not to get hit on a minute-to-minute basis. In places without decent bike infrastructure, strict enforcement just presents a choice between tickets and death.
