I hate it when law enforcement just assumes that everyone is a criminal and just gathers a bunch of data and searches everyone. This is different because they are targeting a group of people that they already know are guilty of a specific crime
They actually didn't target any people at all. They targeted hardware that some people potentially used for a crime. Other people (in the same household?) could have had legitimate privacy concerns.
If I send you a .onion link (which does not easily explain what site is it), you open it, turns out to be a Playpen site, now you're a criminal just like the other because you visited it and got infected?
