The world has become totally digitized over the last couple of decades. Thanks to the Internet of Things [IoT], there are sensors everywhere. They're not just on every street and in every store. They're in your television, your car, your refrigerator, and God knows where else.
If you buy a new appliance today, it's extremely hard not to end up with something that will monitor you. Of course, the argument's made: "Well, if you don't do anything wrong, you have nothing to worry about." I suppose that's true. Here's a tip: you definitely shouldn't commit a murder within purview of one of these devices.
But as Harvey Silverglate pointed out in his book, Three Felonies A Day: How the Feds Target the Innocent, you don't know what crime you may or may not be committing. Your only hope is that the government is too busy or too incompetent to focus on you.
It's probably true that the average person only committed three crimes a day when Silverglate wrote the book in 2009. But so many laws have passed since then that the average person probably commits more like five or six crimes a day now.
So you don't want to make it easy for them to zero in on you, no matter how unlikely that might seem. Nor should you hope the courts will help if you're caught in a Kafkaesque dragnet for some real or imagined infraction. District attorneys, prosecutors, are generally much more interested in convictions than justice. Apart from the fact "justice" is determined by judges, who are either appointed by politicians, or act as politicians when they're elected – and afterwards. Even if a judge follows precedents, he's likely to pick out precedents that suit his personal and political inclinations. So, it's basically a charade. Your first line of defense is to deny adversaries information about yourself.
