Boar copied and took away the electronic files on mutant research. He only recorded part of the paper documents by photographing them; limited by time, he could not photograph the enormous collection of physical records in its entirety.
None of these documents were destroyed. They were to be left for Professor X, to clear the Mutants of wrongdoing and restore them to the role of victims.
Looking at the horrifying photographs in the files and the descriptions of cruel, inhumane experimental procedures, any politician in their right mind would want to bury these materials. That was the leverage Professor X could hold.
It was just that once this leverage was thrown out, the X-Men would effectively be breaking with the authorities.
Even if they could still smile and shake hands for photographs in public, putting on a harmonious front before reporters, it would already be exceptionally civil if they did not openly tear into each other behind closed doors and merely never interacted again.
After all, everything in those files had been done by the U.S. military. This was nothing like after World War II, when the United States took in all the spoils and made leaps in medical technology while Unit 731 of Japan took all the blame for the sins.
Perhaps, under Professor X's leadership, the X-Men would once again prioritize the bigger picture and compromise with the authorities. But how those Mutants chose to respond was none of Boar's business. He had merely handed over the evidence.
All surveillance footage inside the base had been destroyed, including the equipment itself. Whether it was old-fashioned tape-based systems or modern digital cameras, no surveillance system could escape Boar's notice.
However, only footage related to today was destroyed—footage that might have captured Boar or the phantom image of the Skyhawk
