“she may have left a door unlocked”
Leaving a door unlocked is not an excuse for someone to walk on in to rob, kill or maime. Why don’t we have equal rights to leave our doors unlocked rather than sounding stupid if we do? These guys will walk if the defense team can prove a door was open.
Even if a door was open, I'm sure she did not let them into the house willingly, and they had no business being there, so they entered unlawfully.
