Get The Picture

I was watching a movie where the main guys got together and went over some blueprints to decide how they're going to break into a building.

What movie?  Does it matter?  We've seen this moment hundreds of time.

Which had me thinking--can you really get blueprints so easily?  There's never a scene where someone gets the blueprints, they just show up like they're no big deal*.

In fact, when it comes to buildings, I would guess they don't like to give out blueprints for the specific purpose of avoiding groups of people getting together and planning how to break in.

*One famous exception is Star Wars, where the whole plot was built around getting copies of blueprints to HQ, and it wasn't easy.  (And then a bunch of fanboys whined that it was too easy to figure out the Death Star's vulnerability.)
