Given the following context:

Other new North American pop punk bands, though often critically dismissed, also achieved major sales in the first decade of the 2000s. Ontario's Sum 41 reached the Canadian top ten with its 2001 debut album, All Killer No Filler, which eventually went platinum in the United States. The record included the number one U.S. Alternative hit "Fat Lip", which incorporated verses of what one critic called "brat rap." Elsewhere around the world, "punkabilly" band the Living End became major stars in Australia with their self-titled 1998 debut.
The effect of commercialization on the music became an increasingly contentious issue. As observed by scholar Ross Haenfler, many punk fans "'despise corporate punk rock', typified by bands such as Sum 41 and Blink 182". At the same time, politicized and independent-label punk continued to thrive in the United States. Since 1993, Anti-Flag had been putting progressive politics at the center of its music. The administration of George W. Bush provided them and similarly minded acts eight years of conservative government to excoriate. Rise Against was the most successful of these groups, registering five straight Billboard 200 top ten records between 2006 and 2017 with The Sufferer & the Witness, Appeal to Reason, Endgame, The Black Market, and Wolves. Leftist punk band Against Me!'s New Wave was named best album of 2007 by Spin. Politicized DIY punk also sustains active and inter-linked communities across Europe, as demonstrated by independent international events such as Fluff Fest in the Czech Republic.

answer the following question:

In what year did Rise Against release The Sufferer & the Witness?
