You don't need brain surgery or an MRI to scan a brain, this just uses an EEG.
yeah, and then we remember the videos from the good old downunder where the cops assaulted parents, chased kids around, pinned them down, and injected them with experimental drugs that turned out to cause worse outcome for their agegroup.. this was a couple of years ago.
The real battle will be with law enforcement who get a warrant to look at your brain in an MRI.
