Ah yes, the old “government does X, so i’m going to speculate it also does Y, and it’s up to you to prove otherwise” trick. Arguing on the Internet is so much fun when we get to just make things up.
Come on now, there are literally thousands and thousands of thoroughly documented cases of law enforcement and government agencies violating the law.
The Israel == Guantanamo thing doesn't exactly make sense to me either, but now you're arguing nonsense. Certainly, we all know that the government, including law enforcement, doesn't always follow the law.
That's almost the entire argument for putting any limits on governmental power at all.
(That's not to say we should restrict them from doing this, though; if they can crack a phone, good for them, I suppose. But it's another thing to be concerned about.)
There's thousands of law enforcement agencies in the U.S., handling tens of thousands if not hundreds of thousands of cases each year. If they break the law with respect to a small percentage of those cases, you'll end up with thousands of examples. But with respect to any given thing, statistically, the government is probably not breaking the law.
Here, the "Israel == Guantanamo" thing doesn't make sense if you assume that the government is using the Israeli hacks to break iPhones it has in custody because of a warrant or arrest. You can speculate that the government is stealing peoples' iPhones and breaking into them without a warrant, but it's an actual logical fallacy to point to different things the government is doing to argue that the government is doing this thing too.
