Pretty sure that making a deadly situation look like a video game is not a good idea

I'm referring, of course, to the police releasing the body cam video of them going through the school to find the shooter in Tennessee yesterday.  I'll gift link to the NYT story that describes the video.

It seems kind of obvious to me that this has the potential of "selling" to a mentally disturbed person that they too can be a part of a real life video game, and also give them the idea that they would know how to anticipate and deal with the other "player" seeking them.  

Has anyone else been saying this?  I can't be the only person thinking this, surely...
