Depends on what the objective is. The US government has had back doors into webcams, microphones, and social profiles for around two decades now. Snowden exposed the extent of their snooping in the early aughts and it was quite shocking. I doubt they've been resting since then. The stuff that gets leaked is usually the stuff they're fine with people knowing about it. The Snowden leak was unprecedented, and we usually don't get that deep of a glimpse into the intelligence community. By now they likely have complete and total access to anything, a Sneakers Black Box, if you will. No private tool can accomplish that. Keep in mind I'm talking about the NSA, not the FBI or local law enforcement.
