Heres some interesting logic. for spinzaku
Shirley attempts to jump off a building earlier. and lelouch jumps after her. risking his life for her. then leaves her to spinzaku.
spinzaku leaves shirley to a cop. shirley then runs away from said cop into the mall(how did spinzaku not see her?)
also spinzaku overheard about a assassin coming did he not? said assassin could of shot shirley.
and that they say its a suicide, but thats false if rolo was the one who killed her(and he is) therefor the cops lied to spinzaku about her suicide. if she was shot by her gun then rolo's prints would be on said gun, or her arm cause he had no gloves.
if they didn't halfass on determining cause of death they could of found out she was forced to shoot herself by someone who got ahold of her.
