Odd what? That McVeigh was so swiftly dealt with? Not really. His crimes were played out on TV, and some of his victims mere babies (and he knew that in advance). His crime was unique in the annals of American crime history and so it's clear that the public needed and wanted and deserved swift justice. And it was important that the legal system deliver it. That case is an example of our system working. The OJ case is an example of our system not working.
What are you implying? A nefarious plot of some sort??
