Abstract
The text under review, authored by the renowned Spanish professor, Prof. Dr. Dr. Dr. h.c. Juan-Luis Gómez Colomer -which is prefaced by Professor Fernando Velásquez Velásquez to whom it is also dedicated- is, as he himself indicates, an introductory 'manual' to North American criminal procedural law. It is an edition prepared for the Latin American context and, in particular, for Colombia, which brings together three previous research studies: two of them under the coordination of the author and the third, of his exclusive authorship. The text presents a simple but no less profound explanation of the constitutional bases of the U.S. federal criminal system and its operation, based on the analysis of some of the most important cases decided by the courts, particularly by the U.S. Federal Supreme Court.
