The long history suggests that the shows and movies are a symptom of cultural attitudes, rather than a cause. For example, consider all the media in the 1980's portraying criminal procedural protections as "technicalities." I think it was in response to the fact that, after 1960, crime per capita tripled before incarceration per capita started going up. As I said about 24--in the aftermath of 9/11, the torture-fest was just capitalizing on the anger people felt. On my college campus in 2002 there was a lot of talk about nuking the middle east and things like that, which is quite contrary to what the government was saying.
