Nope. That’s not how Signal and E2E encrypted messaging works.
If a government asks Signal for user data they get an almost empty sheet of paper. Search for " what data does signal collect" to confirm that.
If - on the other side - your smartphone is compromised or unlocked there is almost nothing Signal can do to prevent governments from looking into your data. Also it reads like some agents simply joined a group chat. Again: nothing Signal could prevent.







Any software used by enough people will be targeted.
