Principle: The government should not prevent someone from expressing a true belief unless expressing it would be harmful to people generally
Application: The government was wrong to prevent Calista from publicly expressing her belief that there is evidence that cancer rates have increased slightly over the last two decades and that this increase was due partly to excessive use of cell phones
Several studies have found evidence that use of cell phones has been partially responsible for the increase in cancer rates over the last two decades, and it would benefit people to know this.
