The president of the Ottawa Police Association says officers wearing wristbands in support of Constable Daniel Montsion aren't passing judgment on his guilt or innocence.
Montsion has been charged with manslaughter in connection with the death of Abdirahman Abdi.
A pre-trial hearing has been set for May 1st.
Matt Skof said this wasn't a public campaign - it began as a private expression of support by officers in the field.
"This is not making a distinction of the actual facts of the case," said Skof.
"It is saying that they're feeling empathy for a colleague who was called to service, that they, themselves, may have been put in that position."
He added it's unlikely officers would wear the wristbands while on duty.
Chief Charles Bordeleau has pointed out that should not happen, as the bands are not part of the uniform.
Police Services Board Chair Eli El-Chantiry says donning them - even if well-meaning - has unintended consequences and is divisive.
The Justice for Abdirahman Coalition has issued a statement saying it is outraged and disappointed.
It calls the show of solidarity a "blatant disregard for human life."
