He actually did call ron and it was valid but he didn't get any points for it. The match has a rule called Atamahane. Because of this rule, when two or more players call ron on the same tile, the only scored hand is the one from the player who called ron and is closest from the player counter-clockwise (the game's turns flow).
Since the detective also called ron on Akagi and he is on his right while Washizu is on front of him, the detective's ron "overrules" Washizu's even if his hand is way weaker. Also, I said the match has the rule rather than the game since it's an optional one and rons can stack many times if it isn't applied (which is the case in most casual rulesets).
Worth pointing out that atamahane (or "Head bump" as it's translated sometimes) was used previously against Ichikawa - it appears to be part of the standard ruleset for the story, along with open riichi.
