If the cyclist had gone straight at his speed prior to impact, the cop could have either stood still where he was, or attempted to run past.
If the cop chose to walk on, the cyclist would have to swerve one way or another to avoid him.
They both made their choices based on an assumption about what the other would do. The cop assumed the cyclist was going to continue on present trajectory, so he attempted to run past. The cyclist assumed the cop would continue on present trajectory, so he veered left to go round him. They ran into each other.
There doesn't appear to be any malicious intent here, but then I know some people like to slam cops just as much as people like to slam cyclists, so this thread is likely to run and run with loads of idiocy on both sides.
