Kill a cyclist, get community punishment

The recent Regents Street incident:

.... Last week police issued a fresh appeal for information, with Detective Sergeant Jeff Edwards saying: ....
"I also wish to trace any person who may have moved or had any contact with the pedal cycle."

I feel really queasy about this. What are they trying to pin on the deceased cyclist? That prior to being ran into from behind he was behaving inappropriately? That he had been drinking?
Feels a bit like previous discussions in this thread where if the cyclist is no longer alive and able to defend themselves there is forever the suspicion that they must have done something wrong.
