The government should not be able to look at your private data because it is an imbreachment of our rights. The government should only be able to look at peoples private data if they sense they have a criminal history or are up to no good. Other than that we have a right to privacy.
If you are following the law there is nothing to hide. Some people say that it is big brother coming to the real world. I, however, think that this is perfectly fine. The government needs to know who might be doing illegal activities. They can look as much as they like as long as they tell no one.
