We can. This has already happened with the fairly recent SALT TYPHOON hacks. China (ostensibly) abused lawful wiretapping mechanisms to spy on American (and other) citizens and politicians. The news at the time wasn't always explicit about the mechanism, but that's what happened.

China wouldn't have been able to do this if those mechanisms didn't exist in the first place.
