Simon Didn't Say: When Reconstruction Of A Private Search Goes Awry Under The Private Search Doctrine, John G. Chambers

Georgia Law Review

A privateparty conducting an unreasonablesearch of an
individual need not fear the Fourth Amendment as the
proscriptions therein are applicable against only the
government. The government, however, need not fear the
Fourth Amendment where it replicates that private party's
unreasonable search. As such, the Fourth Amendment is
not offended where the government directs the private

party to "reconstruct" its initial search. This
reconstruction doctrine breeds many questions in
application, particularly in the digital context. In
grappling with these questions, this Note demonstrates
that the current law provides no satisfying answers. It
proposes a new test to assess reconstructed private party …

The Grand Jury: A Shield Of A Different Sort, R. M. Cassidy, Julian A. Cook Iii

Georgia Law Review

According to the Washington Post, 991 people were shot to
death by police officers in the United States during calendar year
2015, and 957 people were fatally shot in 2016. A
disproportionate percentage of the citizens killed in these police-
civilian encounters were black. Events in Ferguson, Missouri;
Chicago, Illinois; Charlotte, North Carolina; Baton Rouge,
Louisiana; and Staten Island, New York-to name but a few
affected cities-have now exposed deep distrust between
communities of color and law enforcement. Greater transparency
is necessary to begin to heal this culture of distrust and to inform
the debate going forward about police practices …

The neutron-capture reaction is fundamental for identifying and analyzing the γ-ray spectrum from an unknown assembly because it provides unambiguous information on the neutron-absorbing isotopes. Nondestructive-assay applications may exploit this phenomenon passively, for example, in the presence of spontaneous-fission neutrons, or actively where an external neutron source is used as a probe. There are known gaps in the Evaluated Nuclear Data File libraries corresponding to neutron-capture γ-ray data that otherwise limit transport-modeling applications. In this work, we describe how new thermal neutron-capture data are being used to improve information in the neutron-data libraries for isotopes relevant to nonproliferation applications. We …
