Stop sign/light honoring daily bike commuter here who often scolds cyclists that do not obey the law, but I think you'll find that the statistics do not bear out the danger you present. How many fatalities (or even serious injuries) result from cyclists blowing through stop signs? If you remove the offending cyclist from that stats, I'd guess you're looking at about zero. I do remember a case in PDX a few years ago where a reckless cyclist struck and killed a man, but it is exceedingly rare.
