American law reviews are generally student edited journals with NO peer review process.  Typically, issues include articles written by scholars and professionals ("articles"), as well as pieces written by law students in the course of their studies ("notes", "comments", etc.).  Although it perhaps unfair to generalize, student work may be less authoritative with potential weaknesses in the scope, accuracy, depth, or reliability of the report.  On the other hand, students are often more willing and able to spot new and emerging topics that law professors have not yet approached.
