I was just thinking about how, once this technology is perfected, at how easy it will be to interrogate high value prisoners. Just pop one of these in their head, and tell them not to think about the top secret or incriminating stuff.

this could be a dialog from https://en.wikipedia.org/wiki/Chaos_Walking_(film)

The article mentions that

so I'm assuming other thoughts and interactions had little to no effect.

I’d be interested to compare this to an adult who is brand new to typing on a keyboard (if you could find one!).

What’s the typing speed and error rates over time as the subject practices? How do these compare to the progress with the BCI?

It wouldn't be particularly hard for a trained person to block their thoughts to a brain implant, if the police were trying to read their mind.

If the police are able to implant a device into your brain to get information out of you, I think you're screwed either way as the good 'ol rubber hose method is likely on the table - at least until people commonly elect to do the surgery or the surgery somehow gets to legendary levels of safety in the dystopian future.

Nah. Generic brain reading is not possible in the forseeable future. Everyone's brain works differently. You have to train a machine learning model to recognize specific types of inputs. You likely cannot do pure thought reading.
