4. There are far bigger threats to the right to protest than HR 347
HR 347 is a pretty minor change to existing law, if you read the actual bill it does not go nearly as far as many blogs have claimed. I actually doubt that any protester will be arrested under this law that would not have been arrested under previously existing law, it can only be invoked in certain circumstances involving people under Secret Service protection. There absolutely is some overly broad language in HR 347 which do represent a slow chipping away of our rights so it is bad bill, but on the list to threats to free speech it would not make the top ten.
The real threats to the right to protests are the increased use of riot police and weaponry against protesters, the closing of public areas to protesters, police surveillance of activist groups, these are all much bigger threats to our freedom than HR 347 is.
