Soo... any answer on my question yet? I'm thinking the Mesuem is medium security, which would be a DC 20 computer roll to work the cameras - easily achevable. However, I would need to tack on a +10 in order to do it without anybody being the wiser. That's a DC 30, a roll I'd need to be crazy to attempt, as I'd only have a 3 in 20 chance of making it, and lighting very rarly strikes twice.
Any thoughts? Am I right, or am I missing something?
