The point was, I can understand someone wanting to check that that was what happened, and that, for example, it wasn't the local police finding a convenient group of scapegoats for something that had some other explanation. (Maybe one that reflected badly on them.)

And I'm not suggesting at all that the facts weren't as you have them in the song, or that your interpretation of the hesitation about the song in this case is wrong - just making the general point that wanting to ask questions about an atrocity makes sense.

For example, in Amadou, you mention the attempt by the killers to claim that he had been reaching for a gun. It's been proved that that was a lie. When I sing that song it is helpful to know that.
