Here's an article from Sunday's Philadelphia Inquirer about recent accidents between cyclists and pedestrians in Philadelphia that have resulted in deaths and serious injuries to pedestrians.

At least two Philadelphia residents died last month after cyclists hit them: Tom Archie, 78, who was struck by a bicyclist going the wrong way down a street in South Philadelphia, and Andre Steed, a 40-year-old paralegal, whom police found bleeding on the ground at 16th and Locust Streets after an apparent collision with a bike.

I love to ride and I'll take almost any opportunity to defend the right of cyclists to use the road. But riding against traffic on a one way street in the busy parts of a major city and hit-and-run cycling are indefensible.
