There's a lot of problems with Snap mode and her stealing a gun and killing the cops then Senpai and herself
A. The cops
WOULD notice you trying to take their gun, cops aren't stupid and are
TRAINED for those type of scenarios to happen with any given situation. Plus, Japanese cops are trained in martial arts to take down most offenders, so unless Yandere-chan has the strength of 5 Chuck Norrises she's going down like a sack of bricks.
B. Trying to steal a gun would require you to be able to move your arms and hands and any cop worth their badge
KNOWS how to restrain a person and lock them up with the handcuffs and unless you are Superwoman You ain'tgetting out of those handcuffs. Last time I checked, Yandere-chan is just a teenage girl, Fuck the training at martial arts skill and she's invincible because she's broken hearted or some shit, she's still just your average high school girl! The cops will restrain her sorry ass and she'll get hurt and more charges to the situation.
C. Say if by some miracle she still got a gun, the other officers will still
SHOOT her sorry ass dead. Even if they don't kill her she's still going down because unless she was merely grazed, she will be on the ground in agony unable to move. Plus everyone knows that one gunshot can still potentially kill you by making you bleed out. They are not like bug bites and you can just grit your teeth and power through it like the movies portray it!

R : Unless Yandere Simulator is suddenly portrayed like My Hero Academia, Yan-Chan isn't getting away form the police she's going down. I don't care if the game is supposed to be realistic or not Alex is a moron.
