Sometimes, it is significant that a dog does not bark. In the case of President George W. Bush, there is something noteworthy that he did not do much of in his last few days in office.
Often, politicians use their last days to pardon a large number of people. President Clinton, for example, pardoned 140 people on the last day of his presidency, and during his term he gave pardons or clemency to 456 people. These pardons included quite a few Democratic politicians (for example, Mel Reynolds, Henry Cisneros, Dan Rostenkoswki), big-time Democratic donors like Marc Rich, his brother-in-law Roger, and Susan McDougal, who had shared legal troubles with him.
President Bush, by contrast, was very cautious about issuing pardons throughout his two terms. The Wikipedia article about his pardons reports that he pardoned 189 people, but all of them had served their entire prison term; the effect of the pardon would be to clear their record or eliminate the collateral effects of their conviction, such as the right to vote or own a gun. He also commuted the sentences of 11 people. There did not seem to be a long list of people pardoned at the end of his term.
Of the 200 people pardoned or granted clemency by President Bush, only 5 are well known enough to rate their own Wikipedia article. The best known is Lewis “Scooter” Libby, who received a commutation of his sentence in 2007, but never a full pardon. The two border guards, Ignacio Ramos and Jose Compean, had their sentences commuted. (Most people didn’t think it fair that the border guards received a longer sentence than the illegal alien and drug smuggler that they shot.) The last well-known person was rapper John Forté , who was convicted on drug charges.
Our ex-President is very unpopular right now, but it seems like when it came to pardons, he used his power wisely, and did not abuse his office to pardon political allies. He also did not favor the rich and famous, but rather chose to pardon mostly small time criminals who had long ago served their sentences. I hope that future presidents follow this example.
