| Weren't they able to track Ms. Julie back to the Nazi posters because of the key cards? (Although she defended them so she would have admitted them.)
At Virginia Tech, did the killer let himself into the dorm with his key card? If so, they could have tracked him, after the first crimes.
It really should be that cards are dorm, building, and floor specific. That is how most building security is. Where I work now, cards are specifically programmed to allow access to specific areas of the building where one works. To get exercise room access, for instance, one has to pass a screening and then access is added to the card. |
