A government is justified in interfering with a person's action if the action would increase the likelihood of physical harm to others and the action is not motivated by a desire to help others.
Principle
Action would increase likelihood of physical harm to others govt. justified and → in interfering Not motivated by desire with person's to help others action
Evaluate / Goal
The conclusion should match the right side of the arrow.
So, this principle can only prove that the government is justified in interfering, so we can immediately throw out any answers that conclude the government isn't justified or answers that say someone besides the government is justified.
For answers that correctly conclude "government is justified", we just have to ensure that both criteria are met 1. action increases likelihood of harming others 2. not motivated by desire to help others
