Tim Carney e-mails re: something that has had me wondering, too–and the RNC setup is currently the same; I don’t get it:

Despite unprecedented levels of security at this convention, there is one
detail that strikes me as a weakness. The passes to the Fleet Center are not
personalized with a name or a picture. This means that if any of the
thousands of delegates or reporters loses his, gets mugged and has it taken,
or just gives it to somebody else, then who knows whose hands these passes
can get into? In fact, just outside of the arena tonight, a colleague was
approached and asked by someone on the streets of Boston: “Hey, are you
leaving? Are you done with your pass? Can I have it?”
