This is working as intended, as they mentioned in their streams and the tutorial tip suggests. It was far too easy to steal in D:OS1 and now you can't just go in, loot everything, then walk away clean. It doesn't make sense to be able to do that anyway. If you're stealing things and people noticed that things are missing then they will want to know who stole them. It's possible to talk your way out of it or you can simply resist the bag search. It's a simple fix though isn't it? Don't hang around the crime scene after you've committed the crime? Can't become a very good criminal by doing that.
