The detail of this story that made me re-think the police's position is that the truck turned south on Southwest Boulevard, which rarely has bicycle traffic. 23rd Street, the east/west street, is a popular route for Tulsa rides, as shown by this map:

I did not know Joseph Bartlett, but I think it dishonors him to publish such a weak explanation for his unnecessary death.
