Criminal Masterminds

Last Friday, the property manager of the office building where I work distributed this notice to all the businesses in the building:

This is an important message from [name of person and company deleted].

I want to bring your attention to a recent situation involving downtown buildings. We have had a pattern of thefts from office buildings downtown involving two males and possibly a female. They work by going into an office, distracting the staff and taking personal items from desks, sometimes computers, etc. We are also getting reports of empty or unoccupied office suites having items stolen from them. I will keep you posted as new developments occur.

First of all, there are three let's-call-them criminal masterminds (for reasons I'll get into momentarily) who have assembled for a crime spree and the best thing they can come up with is striking office buildings?

Secondly, how awesome are these thieves that they're managing to steal from "empty" office suites?! What are they stealing, the air?

And finally, how distracted do you have to be for someone to steal the computer right off the desk in front of you?! I mean, what the hell kind of distraction are they using?

Must have more details!
