Examine the logical coherence between the following administrative actions and the provisions of the National Security Act, 1980:
1. Evidence 1: The NSA was enacted to protect the defense and security architecture of the entire nation. Inference 1: Therefore, the statutory power to authorize a detention under the NSA is exclusively vested in the Central Government.
2. Evidence 2: A state government utilizes the NSA to detain a local gang leader to prevent severe disruption of public order. Inference 2: This action is legally valid because the NSA explicitly empowers state governments to issue such orders.
3. Evidence 3: A foreign national is caught planning espionage activities within Indian territory. Inference 3: The government cannot use the NSA to detain them, as the Act's definition of 'person' is strictly limited to Indian citizens.
