It seems a fair number of folks are focusing on the door not being properly locked. It doesn’t matter . Breaking and entering doesn’t mean you have to “break” something to get in. It means you are entering someone else’s property without their permission. You can’t just wander your neighborhood trying doors until you find one unlatched and then enter and help yourself to whatever. If you see the owner you can just shout panicked orders and then shoot them. One of the things that bothers me most about the case is that even when she realized she had fxxked up she didn’t make any effort to aid the innocent victim. That’s callous disregard for life.
I would think that the word "break" has to apply if you are going to claim "breaking and entering."
Entering yes, breaking no. Accidentally entering someone else's apartment, car or house is not a crime.
