The clear-and-present danger rule dictates the following: That citizens are required to evacuate an area until further notice
That the government can prevent an act of free speech if it is linked to an unlawful act
That the government encourages citizens to speak out against criminal activity
That the country is at risk for going to war

The clear and present danger test features two independent conditions: first, the speech must impose a threat that a substantive evil might follow, and second, the threat is a real, imminent threat. The court had to identify and quantify both the nature of the threatened evil and the imminence of the perceived danger.
