Response to: Jennifer E. Laurin, Trawling for Herring: Lessons in Doctrinal Borrowing and Convergence, 111 Colum. L. Rev. 670 (2011).
Though she provides ample analysis for most of her many insights in Trawling for Herring: Lessons in Doctrinal Borrowing and Convergence, Professor Laurin never actually explains her article's title. Curious readers may well wonder exactly what it means to "trawl" for Herring. Is this just a simple pun on hapless Bennie Dean Herring's name, or is there more to it? At the risk of ruining a good joke, I suggest that "trawling" is in fact a conceptually significant metaphor that helpfully illuminates the "lessons in doctrinal borrowing and convergence" heralded in Laurin's subtitle. Indeed, the trawling metaphor builds upon a second water-based metaphor-the "hydraulics" of borrowing and convergence-that together animate Laurin's bold theses about the true origins and future trajectory of contemporary exclusionary rule doctrine.
