Now, I work in computers (not NEARLY at the level BC and those folks do). I have said from the start that the time stamps and other stuff was just a computer glich.
But I think what is happening is that we are looking SO deep into the computer stuff that we are missing the BASICS of networking. Now most of us have a home network, either wired or wireless (I have both). And MOST of us that use wireless, use the commercial WPA or WPA2 security. In other words, you have the stuff YOU put on your network, and if a friend comes over with a laptop, or with a WiFi phone, they try to connect, it asks for a password, you give them the alph-numeric code you set up when you installed the router.
Now, in order to believe that BC accessed the PC while it was in evidence, you have to believe that a POLICE STATION, with a lab specifically designed for computers, also has a COMPLETELY UNSECURED wireless network. Now many places of business have mulitple wireless networks for different uses. They might have a highly secured one for company business, a lighter secured one for personal employee use, and an OPEN one for the general public (such as in becoming more common in bars and books stores, etc). But I would doubt a POLICE station would have an OPEN network. What would be the reason? SO that perpetrators could surf the net while awaiting booking?
Now, ON my network (I have one private network), I can see who is CURRENTLY connected, and who HAS connected and has permission to connect again, etc. I would think that a POLICE STATION would have something similar.
People seem to be talking about this "Cisco VPN" like it is a MAGIC connection, but while you CAN make a secure connection over the Cisco VPN, you STILL have to have the network connection to the PC in the first place. Its not like an astronaut could take the PC to the moon, turn in on, and someone in Miami, working for Cisco, can access it.
