This is a little bit of info on what the government can do.
-Police can examine the contents of your smart phone without a warrant
The supreme court is reviewing two such cases (United States v. Wurie and Riley v. California). This is how it works. Police can search for evidence that could be destroyed by you and weapons without a warrant. They use this excuse to go through phones throwing your fourth amendment rights out the window. Unfortunately in the review they are not talking about the constitution at all. Their all focused on privacy instead of property rights. If these cases swing the wrong way just expect your phone to be subject to inspection any time a cop wants it.
-Local law enforcement as well as most government agency's can access your emails, social media message and cloud documents without a warrant.
Electronic Communications Privacy Act (ECPA) permits this and quite a bit more.
-You can be held indefinitely in a military facility without charges
In the National Defense Authorization Act you could find yourself with no rights what so ever due to other peoples actions in a group you are associated with. Section 1021 expresses that nobody is exempt regardless of their citizenship. The act is interpreted as something that can happen by a presidential action but doesn't require it to be.
-The president can kill you without a charge, trial or evidence
This one is fun. 2001's Authorization for the Use of Military Force authorizes the president to pretty much have you executed. Will it happen? Probably not. That would be political suicide. But it is in his power. The DoJ White Paper explains how in very vague terms. https://msnbcmedia.msn.com/i/msnbc/se...hite_Paper.pdf
Whats really disturbing about this is that the process of deciding who gets killed is top-secret and even congress has no idea how it works.
-The FBI, NSA, and CIA can turn on your cell phones cameras and microphone or your computers web cam with no warrant.
There are a couple acts that allow this. I doubt this one is news to anyone.
I could probably go on and on with this stuff. If people want to know more I will dig it up. Pretty scary to know how few rights you actually have.
