Interview with "UFO Hacker" Gary McKinnon: why'd he do it?

Snip from Nigel Watson's Wired News interview with so-called "UFO hacker" Gary McKinnon, who faces 70 years in prison and a $2 million fine if convicted:
Gary McKinnon: A NASA photographic expert said that there was a Building 8 at Johnson Space Center where they regularly airbrushed out images of UFOs from the high-resolution satellite imaging. I logged on to NASA and was able to access this department. They had huge, high-resolution images stored in their picture files. They had filtered and unfiltered, or processed and unprocessed, files. My dialup 56K connection was very slow trying to download one of these picture files. As this was happening, I had remote control of their desktop, and by adjusting it to 4-bit color and low screen resolution, I was able to briefly see one of these pictures. It was a silvery, cigar-shaped object with geodesic spheres on either side. There were no visible seams or riveting. There was no reference to the size of the object and the picture was taken presumably by a satellite looking down on it. The object didn't look manmade or anything like what we have created. Because I was using a Java application, I could only get a screenshot of the picture -- it did not go into my temporary internet files. At my crowning moment, someone at NASA discovered what I was doing and I was disconnected. I also got access to Excel spreadsheets. One was titled "Non-Terrestrial Officers." It contained names and ranks of U.S. Air Force personnel who are not registered anywhere else. It also contained information about ship-to-ship transfers, but I've never seen the names of these ships noted anywhere else. WN: Could this have been some sort of military strategy game or outline of hypothetical situations? McKinnon: The military want to have military dominance of space. What I found could be a game -- it's hard to know for certain.
