The chances of a constitutional amendment, let alone one dedicated to specifically limiting the powers of law enforcement, is, and I'll go on a limb and say I'm correct in this absolute statement, 0.
There is zero chance of any amount of government in these United States cooperating in any fashion large enough to change the actual Constitution. Zero.
I'm not so sure about that. A while back Virginia managed broad bipartisan support to curtail ALPR usage. Unfortunately the governor vetoed that IIRC.
Being creeped out by corporate stalkers and an invasive government seems to be something that a lot of "regular people" of all political allegiances have in common.
I still think these things can be worth pushing for, it's an issue that even the older conspiracy theorists I know naturally understand. There's a persuasive use to advocating for something simple and a constitutional amendment on privacy doesn't need much explanation (unlike some laws that people propose). If it gets some support we probably won't get an amendment still but we might get some concessions (even if it's just an amendment to a budget bill, which seems to be the only thing this Congress can actually pass).
Currently true, but doesnt mean there "shouldnt" be one right?
It could be done if two thirds of the states call a convention which might actually be more likely than getting Congress to agree on anything, I'm just not confident the red states would go for it.
