Cyberlaw HR4681
David Cameron recently proposed banning encryption, Obama sided with him, now Obama introduced yet another insane proposal to update the US CFFA law against hacking.
If you click a link that contains illegal material, leaked information, if you're in an IRC channel or a online conversation, a forum, a chan, a Twitter discussion and some people are talking about hacking or something else illegal, even if you have nothing to do with it, if you go to Wikileaks, if you access leaked Snowden documents you can be prosecuted and sent to jail for up to 10 years.
This will restrict freedom of speech, and basically remove the first amendment in terms of the internet. Along side this, it could be used to get some one arrested. Send an illegal link, and you can get any one arrested.
