No dumbass, murder has to be premeditated and/or intentional.
Shoving someone out of your way/down doesn’t imply that you intended for them to actually die. And it’s pretty hard to prove that you did in court.
Manslaughter - the unintentional act of killing someone through irresponsible or negligent actions - is a fucking slam dunk here. You want this sour bitch to walk free because the prosecution couldn’t get a conviction, because laws are written more specifically than the few words you learned in school?
Go away. Adults are having a conversation, sweetie
