I also run redlights and stop signs. I realize that I am breaking the law, and I am willing to be held responsible for my actions if something should happen. I have never put myself or others in danger when doing so. I have never run a redlight with cars coming or almost been hit or hit any one at a stop sign, so I don't think my actions reflect poorly upon cyclists. I'm not doing anything dangerous to myself or others. I also (reluctantly) agree that cops are responsible for upholding the law, and if they see fit, they could issue me a ticket and I would be deserving of it according to the law.

Edit: I forgot that some people are idiots... If people are being dangerous and causing injury, then obviously it is the cyclists responsiblity to pay for damages, and if need be, the police would get involved in the matter to inforce this. I think that by saying that it is "everyone's" responsibility, you would be saying it was my responsibility to make sure everyone was riding safe. That makes no sense. I can't stop you from doing something and I can't change your actions in the future just by vocalizing my opinions.
