Here is a link to a few cases of interest that were provided me last week at the 49th VACLE Criminal Law seminar.

United States v. Abdallah, ___ F.3d___ (4th Cir. 18 December 2018). Code 45 Alumni and friend Jim Wynn is one of the panel members. This case involves two issues: invocation of the right to silence and the all-important Brady issue.
