Final answer:
There is no specific reference to an Article 9 within the Canons of Police Ethics in the provided information. Legal restrictions under Article 1, Sections 9 and 10 of the U.S. Constitution protect personal liberties against government encroachment.
Step-by-step explanation:
Article 9 of the Canons of Police Ethics seems to be confused with various legal documents and ethical guidelines. However, based on the information provided, there is no direct reference to an Article 9 specifically within the Canons of Police Ethics. When discussing legal and ethical frameworks, it's important to reference the specific document accurately. In terms of ethical guidelines for law enforcement, the International Association of Chiefs of Police has set out a Law Enforcement Code of Ethics which emphasizes integrity, service, and respect for the legal rights of all individuals.
Meanwhile, Article I, Sections 9 and 10, of the U.S. Constitution detail restrictions on federal and state authority, including the prohibition of suspension of the writ of habeas corpus, bills of attainder, and ex post facto laws. These restrictions are in place to ensure that the government does not infringe upon personal liberties and are supported by the Bill of Rights.
