  This work proposes a method for the measurement of a country's digital
investigation capacity and saturation for the assessment of future capacity
expansion. The focus is on external, or international, partners being a factor
that could negatively affect the return on investment when attempting to expand
investigation capacity nationally. This work concludes with the argument that
when dealing with digital crime, target international partners should be a
consideration in expansion, and could potentially be a bottleneck of
investigation requests.
