Ngl I don't think they should've changed Dally's death in the musical. The scene where he dies that they went with in the musical is really beautiful and Pony's monologue makes me sob every time but I think the death being like it was in the book and movie would've been an interesting commentary on not just the time period but also Dally's character. The musical already touches on police brutality, we can see them beating on Dallas after interviewing him, and also how the cops don't really care about the greasers. I think Dallas getting shot by the cops in an assisted suicide is really important. He's just a kid, 17. He carries an empty gun because he is worried about getting jumped, not because he wants to hurt someone with it. He's just a scared kid. A scared kid who gets the cops to shoot him cause deep down he's scared and grieving. I don't think Dallas committing assisted suicide should've been cut because it shows an interesting side of his character. Police brutality is already a topic in the musical, I don't think him being shot would've been too far and I think it'd get more people talking about the fucked up shit cops are depicted doing in the musical. Dallas was a poor black man in the 60s in Oklahoma and it's not unrealistic that police brutality would be portrayed.
