If u want to escalate the shit out of it but 1000% solve the problem: 1)Tell her tht if she can’t lock the door when she leaves then u wont either 2) after like a week of leaving the door unlocked pretend to leave for work, leave the door unlocked, wait for her to go to sleep and then will dressed like a robber either u or a ( very well) trusted and preferably gay male “break in”and “assault” her She may be traumatized but I’d bet money tht she’ll nvr leave tht door unlocked again
In my state, breaking and entering is defined as entering an occupied building without permission and with (felony) or without (misdemeanor) the intent to commit a felony. Even if the door is unlocked if you don’t have permission to be there, which the roommate would not grant, it’s B&E. It’s even clearer because they would enter her room, not just common areas. No ambiguity of “I was hanging out with rm” The assault with specific intent to “teach her a lesson” is felony assault and felony B&E
