Roommates keep leaving doors unlocked

My roommates keep leaving the front door unlocked when they leave the house and a few different times I’ve gone out to the living room at night and the door will be unlocked and I’ll be completely home alone. God told me to go check the locks just now and low and behold, both the back door and the front door were both unlocked. We live in a what people have described as a “ritzy” area and the neighborhood is very safe but still crazy things happen all the time. I’m just so frustrated. I don’t want to bring it up because I have accidentally left the door unlocked too, but in the morning in a rush never at night . Would it be hypocritical of me to bring this up ?
