Furthermore, the officer's request that Hiibel identify himself did not implicate Hiibel's Fifth Amendment privilege against self-incrimination. There was no "articulated real and appreciable fear that [Hiibel's] name would be used to incriminate him, or that it 'would furnish a link in the chain of evidence needed to prosecute' him." Because Hiibel did not articulate reasonable belief that his name could be used as an incriminating piece of evidence, he could not invoke the Fifth Amendment privilege in refusing to disclose it.
