Google Maps 6.0 includes indoor mapping

Google has created an inside mapping were people can easily connect from their phones and view were inside the store things can be found like an exit or an  atm .It is very interesting how things can be much easier to find inside a big mall instead of having to walk around  asking people were you are. At the same time I think it can be kind of odd because what if people tried to get in and hack the hold system for a mall or some company? Can this happen I guess we will have to see what happens with this.
