"This report’s analysis of law enforcement demands for exceptional access to

private communications and data shows that such access will open doors through which criminals and malicious nation-states can attack the very individuals law enforcement

seeks to defend. The costs would be substantial, the damage to innovation severe, and

the consequences to economic growth difficult to predict. The costs to developed coun-

tries’ soft power and to our moral authority would also be considerable. Policy-makers

need to be clear-eyed in evaluating the likely costs and benefits. It is no surprise that this

report has ended with more questions than answers, as the requirements for exceptional

access are still vague."
