Here is the senate page on the Bill https://www.judiciary.senate.gov/press/rep/releases/graham-c...

> Bad actors exploit warrant-proof encryption to shield dangerous and illegal activity —including terrorism, child sexual abuse, and international drug trafficking — from authorities.

Bad actors also exploit warrant proof use of their voice to send sound waves directly at other bad actors ears to shield dangerous and illegal activity —including terrorism, child sexual abuse, and international drug trafficking — from authorities.

I realize that end-to-end vs speaking verbally is a bit of a leap but bills like this make it seem like they don’t want US citizens to have a voice.
