From the United States Senate Committee on the Judiciary:
The Lawful Access to Encrypted Data Act is a balanced solution that keeps in mind the constitutional rights afforded to all Americans, while providing law enforcement the tools needed to protect the public from everyday violent crime and threats to our national security. The bill would require service providers and device manufacturers to provide assistance to law enforcement when access to encrypted devices or data is necessary – but only after a court issues a warrant, based on probable cause that a crime has occurred, authorizing law enforcement to search and seize the data.
I don’t expect our elected officials to understand every little detail of how something like encryption work, but legislating that companies keep backdoors defeats the purpose of encryption and privacy.
Tech companies are already helping when a warrant is provided. As an example, Apple already provides a ton when asked to by law enforcement. Eliminating encryption is a bridge too far.
