Just fyi, the police can conduct a search warrant, to seize your devices (i.e. smartphone, computers, digital cameras, etc) if they have sufficient proof of you engaging in illegal activities online. And once your devices are at a digital forsenics labatory, you are cooked.
If you don't have full disk encryption on your computer, then they can see everything on it, simply by removing the internal hard drive (and no, a screen password can easily be by-passed by law enforcement) by examining it with digital forsenics tools. They can see all of your files, if you don't have full disk encryption on your Operating System (OS).....not only the files stored on your computer, but also the deleted files, which files you opened on your image viewer/video player, which files you copied and pasted, your Internet cache/history, etc.
Of course, you shouldn't be engaging in anything suspicious enough for such a search warrant to ever occur (in the first place). But it isn't difficult to use full disk encryption with Veracrypt or Diskcryptor on Windows. Or simply with LUKS on Linux. Such encryption is useful for protecting your data in case if your computers gets stolen/lost.
Hopefully, this information was useful. And have a nice day.
