A statue of the futuristic film crime fighter RoboCop standing guard over Detroit is not in Mayor Dave Bing's plans for the city.
That response from his office to the idea left on Mr Bing's Twitter page spurred some online debate.
RoboCop on Tuesday was a top trending topic on Twitter.
Some tweets - either genuine or tongue-in-cheek - say a statue of the metal alloy-encased cyborg from the 1987 science fiction movie would help bring visitors into the city.
Others argue such a statue would play to the perception that Detroit is plagued by crime and violence.
Spokeswoman Karen Dumas said the mayor's social media manager responded to the RoboCop suggestion, though Mr Bing on occasion does respond to tweets.
