If we are talking about treason - which hanging politicians from a lamp post would be - it won't be crowd control with tear gas and riot shields. It will be some police/military with guns vs citizens/police/military with guns.
Fortunately this law will not require that level of trouble. It is so draconian that it will not pass - so long as it is made public. The only way the government can control us is through secrecy. When something is so obviously against the public interest it won't be passed if enough people fight against it. The reason the Patriot act and others stood was because they just didn't effect enough people. If you start talking about losing your internet because your son posted a YouTube clip, voters will get mad.
