i have attended the psac meetings for a very long time as a member of the public. and i noticed that the one advantage i've seen with the psac, really a great advantage, is its continual organization. it obviously reports to the board of supervisors and it has the capability of really having a strategic function and for that reason as i have attended meetings i've thought, well, we do, the psac has a lot of input from various organizations on traffic calming, on street modification, and one of the suggestions i did make not too long ago was that the police should really, we should step back, the police should really give us an idea of how well are we doing with regard to pedestrian-vehicle accidents including the number of fatalities. in a periodic sense so that we have some idea of how well the city is doing compared to the -- with respect to the metrics that will come out of the mayor's goals and in fact in comparison with other cities in america and throughout the world. my view is that we're dealing not only with tragedy but we're dealing with health issues, he
