Very striking to see how the sentiment has drastically shifted, while the facts of the case did not. There is a really cultural shift visible in how this issue is seen on here.
The attraction for people to post on Hacker News is mainly to complain, and so in the first you get complaints the sentencing is too harsh, and in this one you get complaints that he shouldn't have been pardoned. Its not necessarily a cultural shift, just an artifact of the types of discussions people have online.
