I have crossed a road at a run to beat an approaching car before, and had I been struck it definitely would've been my fault for not practicing proper safety.
I'm with you on this, however, the speed of the cop is an issue. At three times the speed limit, an approaching car would reach you much faster than you would expect it too. This girl may have glanced, seen the cop in the distance, and never realized how fast he was going. Frankly, if an emergency responder if taking an action this far outside the norm, they should also be taking great care because innocent bystanders cannot be expected to anticipate the responders actions.
When I go to bed I put my pill bottle in one place. When I take the pill in the morning, I put it in a different place. I've considered buying one of those timer bottle caps. They fit generic pill bottles and have timer built into the top. You can look at the timer and see how long it's been since you opened the bottle last.
