Examine the logical coherence between the following travel scenarios and their constitutional protections:
1. Evidence 1: A state government enacts a law prohibiting non-tribal citizens from moving freely through specific, sensitive indigenous forest reserves. Inference 1: This prohibition is a constitutionally valid 'reasonable restriction' under Article 19 to protect the cultural and property interests of Scheduled Tribes.
2. Evidence 2: In 1978, the passport of a prominent journalist was impounded by the government, preventing her from leaving India. Inference 2: The journalist successfully argued before the Supreme Court that this action violated her freedom of internal movement guaranteed under Article 19.
3. Evidence 3: Article 21 protects personal liberty against arbitrary and unfair executive action. Inference 3: Consequently, the Supreme Court ruled that the right to travel abroad (external movement) is an intrinsic, protected component of Article 21.
