King gave his speech in Cobo Arena after marching down Woodward. Hart Plaza hadn't even started construction until over a decade after the speech. It was empty land used for parking. So King walked past a parking lot, which makes the parking lot a historic landmark, so the park that was built on that land should be renamed after King?

Phil Hart is one of the greatest political leaders we have ever produced, and was universally respected. He lived up to every ideal of American democracy in a way that few ever have.

King of course is a more important historical figure, but he's not a Detroiter. He gave a lot of speeches at a lot of places as part of his work in the civil rights movement, and Detroit was just one of them. If we want to honor him we could start by keeping the things we've already named after him in decent condition.

Also I don't think the guy mugging you at the gas station is really thinking about what Hart Plaza is named.
