We can't solely blame gamers. The game developers made the museum a Poke Stop, which gives players in-game rewards. According to the Post, there are three stops in the museum. Nintendo has yet to comment.
The museum's communications director said he's trying to get the museum removed from the game.
If you think the U.S. Holocaust museum was the only somber place for a Poke Stop, you're wrong. The National September 11 Memorial & Museum also has them.
But a security guard at the memorial told The New York Times he hasn't had any problems with players.
