I think this line
The survey asked 1,042 Americans a number of questions regarding various civil rights, in the light of the recent terror attacks in both the US and abroad.
Sums up alot, Terrorism abroad. Americans are probably the most skittish of people on the planet. Despite the fact the news leaves out alot of terrorist attacks now. Sure the serious ones get coverage, but the smaller ones like Bomb vests, and kidnappings. Nope nothing. But the moment they get wind of it. "need to deploy troops" "Take my freedoms! take my privacy! keep me safe" Seems to be all you hear.
Out of all the survey respondents under 30, only a third supported the idea of warrantless Internet surveillance. In contrast, two-thirds of Americans over the age of 30 supported the idea.
And here is good evidence of a generational gap, between people who understand how Internet affects there modern life. And how the older set are less worried and more willing to give it up, as it played less of an important role. Alot like how the Chip&Pin system took so long to get root in the US. People there just keep alot of status quo lifestyle.
But as mentioned, its only 1,000 people and that small of a group changes answer's due to dumb luck. Maybe they hit more Scared of terrorism people that day then not. Sadly these are the polls politicians love to quote and use for new law making, so it counts.
