(Calero-Toledo v. Pearson Yacht Leasing Co. (1974), 416 U.S. 663, 40 L. Ed. 2d 452, 94 S. Ct. 2080.) Although Calero-Toledo did not involve the double jeopardy clause of the fifth amendment, the Court in that case emphasized that a forfeiture proceeding is brought against the instrumentality of a crime, rather than against the offender himself. The Calero-Toledo Court noted that the object of the forfeiture is “ ‘primarily considered as the offender ***. [T]he practice has been, and so this Court understand^] the law to be, that the proceeding in rem stands independent of, and wholly unaffected by any criminal proceeding in personam.’ ” (Calero-Toledo, 416 U.S. at 684, 40 L. Ed. 2d at 468, 94 S. Ct. at 2092, quoting The Palmyra (1827), 25 U.S. (12 Wheat.) 1, 14-16, 6 L. Ed. 531, 535-36 (<HOLDING>).) The Calero-Toledo Court also noted,
