Each country hosts their own laws and regulations, so to stop information that is unwanted from entering the country we could no longer use the world wide web, instead it would have to be a US only system that blocks contact from any other outside source, like places in North Korea, and china have done, countries that we vehemently disagree with regarding their censorship due to our declaration of free speech. Placing restrictions on the information put on the internet is hard to do without siphoning off every text with keywords in it. This purpose of safety can easily lead to a downward spiral of every bit of information being accounted collects, and held against you by the government, like a parent reading every page of your diary in order to see if you were doing drugs, even though they had no reason to suspect you were doing drugs. If every piece of information was read by the government free speech no longer exists, and giving the government complete access to the internet opens them up to every call, text, snap, insta, facebook, or blog that you have made because all of that information is stored on the web. Discriminating between the personal information stored on the web and pertinent information regarding security has no definitive boundaries. The abundance of gray space between security monitoring and a big brother society leaves it hard to define what is protecting us from using the internet as an archaic playground to wreak havoc without fear of punishment, but not as far as leaving people to writing paper notes that they burn after reading in fear of being punished for their conversations. In fact only 6% of the population feels secure in that the government is keeping their records private and secure, but like Snowden's reports, the government has covered up and kept hidden what personal information they are collecting over the internet and we truly don't know
