In answer to the OP's question if we should censor people's content, I have a few questions of my own.
Where would it stop? If we censor one thing, it will lead to another.
Who would be responsible to oversee this project? We don't need another taskforce or Tsar of anything. We have a difficult time even monitoring the things we're supposed to, like bank regulations, drug companies, and food safety.
Would you have us become like China, where the internet is locked down and people chat to each other in code because the words they want to use are blocked by the system or would send up red flags that would end up having them tailed, harassed by police, and even jailed. (This is my personal opinion, only based from things I've read in the news. Sorry have to make that disclaimer.)
Would you have us end up so that every single thing we upload, whether it be a photo on Flickr, or a short youtube video on how to make braised ribs, go into one ginormous queue where some worker is paid to deny or approve what you wanted to post? Can you imagine the backlog, or the potential abuse of power to censor other things indiscriminately? How would any agency ever keep up?
Then we have the whole government/civil liberties angle to address. To have every aspect of your life scrutinized for a possible mis-step is very much intrusive and invasive (and that's what you're suggesting, because how else would you ensure that no one broke this law in order to prevent something like the events Libya from happening again). This scrutinization would break the fundamental principles that the United States of America were founded upon.
And where would it stop, this monitoring? Personally, I don't think it would.
