Do you believe nsa surveillance is a good or bad thing?

It's bad.

Even if you ignore the violation of the 4th Amendment(which is a much more important amendment than people think, it's the amendment that keeps Justice Objective), it's inefficient.

Big-Data(collecting all data), MetaData(data about data), and general Data-mining, has a big problem, you bury yourself in data, hoping to find a needle, in a needle-stack that is growing explosively from minute, to minute. Add to that, that they're also spying on people we KNOW have nothing to do with terrorism like Angela Merkel, which puts ??? to what exactly they're spying for, and on, is it just for security, or are there economic-interests being catered too(which is an abuse of the system, in a big way).

That's also why till now, the data hasn't been used to initiate any action, the data has been used to 'look back', and verify, after intelligence came from different sources. Because it's too much data to use actively.

And if it's just a database, an archive, it's way too expensive, and there's much more 'to the point' ways to get that info.

Should we endure another attack on the scale of 9-11 that could have been prevented by having better intel the people now upset about the NSA who actually aren't and never have 'listened' to phone conversations (How many millions of people would that take?) would be all over the administration for 'failing to protect this country'!

No. I don't want them to know what I do at night o_0. Anyway, that is what they do. Basically perverted hackers, but they have the legal right to do it. This information isn't being used to target terror, it's used to target people the government considers a threat. Not necessarily people who actually are terrorists. Watch out. They could get you.

Not to mention that it's hurting American business interests as companies from other countries refuse to buy computers made in America because of reports that they may have been bugged by the NSA.

Obviously some people who believe that they are OUR LEADERS think that the end result of catching even ONE terrorist after spending billions of dollars and violating the privacy of millions of citizens is worth it.

Hence the NSA surveillance

There are only two logical conclusions

1. Idiot leaders are ruling

2. The real powers have ruled that their interests supercede that of all( everybody else in this world)
