I guess they do, but unless we have the gloves already it's another thing we need to obtain.
Military operatives on a black ops mission without any gloves? My suspension of disbelief for Hellraiser's artistic license has limits and a black ops team not bringing along gloves or appropriate clothing is definitely crossing over that line.
And even wearing gloves I'm not sure a battle-scarred soldier...
Scars don't mean anything. You should see the tattoos on the workers and builders doing regular maintenance around various universities.
...who can't speak Spanish is going to fit in in a bunch of students during the day.
We don't need to speak. We just need to act and carry ourselves in such a manner that we don't get spoken to and need to reply.
What if the card flashes up a photo of the registered user when entering, as most security cards these days do?
That would only matter if we would need to show the card to a human. For access control, the card would have either a magnetic strip or an RFID chip and we would only need to swipe it through/wave it in front of the reader and we're in, no matter what picture is printed on it.
I realise there are risks to breaking in at night, such as an alarm going off and us being apprehended before we can escape, but I also think there are risks in trying to follow people around the campus, steal their access card, and then use it to access the library in full view of the staff. We are soldiers after all, not professional spies and I doubt we can be very unobtrusive.
We don't need to stalk one individual all over the campus for a whole day. The vast majority of people on campus will be carrying an access card. We need to pick out of the crowd someone careless with his/her card and act. All we need is patience and a little sleigh of hand. Borg has the patience, with him being a hunter and everything. As for the sleigh of hand part, that's why we're sending two people in: to be able to assist each other in completing their mission. One can run interference while the other lifts the card from the mark, or something of that sort.
The library staff won't even bat an eyelash because you swipe, you get it, you go in the library and look for a computer. Unless you start doing truly foolish while you're in there, then nobody will notice anything. This is one of the weaknesses of electronic access control that old school guard at the gate setups didn't have: the staff will trust the system implicitly and, if you can fool the system, the staff will never bother you because of their trust in the system. The people are never on their toes because they consider the system infallible.
So I suppose the balance in voting between C, D and E lies in how everyone weighs those relative risks.
Risk assessment is based on knowledge. If you have incomplete information, your risk assessment is going to be flawed. The reason I have been writing all of these posts is that many may not be aware of what it entails to get to a networked terminal in a college environment.
