Why aren’t these people doing the threatening hunted down, arrested, and prosecuted to the fullest extent of the law.
These are not idle threats.
The threats are physical harm with the intent to silence speech.
This is not just about assualt or a random act of violence from a nut case.
These are real threats, real tactics by a large group of people.
Hunt them down, arrest them, and prosecute them for crimes against the American people and crimes against humanity.
To answer your own question, you need to do two things, both include the ability to read and listen: 1. Observe who is making the threats,i.e. their political beliefs, and their political leaning.2. Who the threats are made against. To illustrate: Tell Bill Clinton you do not wish to shake hands with him and one is arrested. Encourage the assassination of President Bush and make motion pictures depicting his assassination, nothing happen to those. Advocate publicly for the killing of Donald Rumsfield{sp?] nothing happens.
