SCOTUS will simply say that since the constitution didn't explicitly state that electronic data and communications was protected, then it isn't.
Even if it did explicitly say that this information is protected, SCOTUS would just make up a new interpretation that would allow surveillance anyway. Same as they made up presidential immunity, even though all men being subject to the law was pretty explicit purpose of the founding of america. I mean, they had a whole revolution about it.
Text, phone calls and emails which are not encrypted are the equivalent of a postcard. They don't need to seize the effects, only observe them.
Encrypting, end to end, would be the equivalent of posting a letter. The contents are concealed and thus are protected.
Time to wiretap all of Congress and then have a bot post it all to mastodon...
Except, wiretapping was considered very illegal in the USA.
> all men being subject to the law was pretty explicit purpose of the founding of america. I mean, they had a whole revolution about it.
I don't think it is a feasible claim. Revolutionaries, by definition it seems to me, believe some men and the enacting of their principles are above the law. A revolutionary is someone who illegally revolts against the current law.
And formally recognising presidential immunity isn't really as novel as the anti-Trump crowd wants to believe. If presidents were personally subject to the law for their official acts, most of them wouldn't be in a position to take on the legal risk of, eg, issuing executive orders. If something is done as an official act then the lawsuits have to target the official position and not the person behind them. That is how it usually works for an official position.
I think it wouldn't be unreasonable to expect the law to distinguish between official acts taken in an honest attempt to benefit the nation, and those taken to corruptly and brazenly benefit oneself.
That'd be a massive break from tradition in the US. AFAIK the only formal mechanism they have to separate the official from the person behind the role is impeachment by Congress. Apart from that there isn't really a mechanism to handle brazen corruption.
And US presidents have a long history of corruptly and brazenly benefiting themselves. Sometimes you see those before-and-after charts showing how much money they make while in office in excess of the official salary. The typical modern US president makes at least 10 of million in office and it isn't from the salary. Nobody likes it, but there is an open question of what exactly can be done about it.
