According to Herbert Packer in an article for New Republic (January 10, 1970, 12-13), "Gideon 1963": "made it essential for the states to afford the effective assistance of ounsel to criminal defendants." It should also be notes that Miranda v. Arizona established the basis of Miranda rights (a frequent cop film/ cop show trope). In essence, what Packer calls the "procedrual revolution" in law occurs in the 1960s, ensuring more and better rights for alleged criminals. This occurs though, in the supreme court. The legislative response, and still the law enforcement institutions themselves are much slower to change in accordance with these decisions.
