However, those other respondents to your post seem to be accurately describing the current legal situation. I asked Gemini, and apparently "conspiring" to commit an offense requires an agreement with another person in both my country and the US, where an "overt act" is also required (that may not be incriminating by itself). I find this alarming. The fact that someone's private diary entry describing in detail a plot to kill me does not amount by itself to anything is... incredible to me.
