Law enforcement is increasingly facing challenges due to the phenomenon of "warrant-proof" encryption. Service providers, device manufacturers, and application developers are deploying products and services with encryption that can only be decrypted by the end user or customer. Because of warrant-proof encryption, the government often cannot obtain the electronic evidence and intelligence necessary to investigate and prosecute threats to public safety and national security, even with a warrant or court order. This provides a "lawless space" that criminals, terrorists, and other bad actors can exploit for their nefarious ends.
