Their crime was that they agreed to the (ET) approach to running the world and convinced themselves that they were positive.
Already in the 40s 50s and 60s we were tested on whether we were ready for independence and it seems that a handful of people preferred to hide the truth and cooperate with the evil rather than tell the world the truth.
They offered us technology and medical knowledge. It all stopped as soon as we cooperated with the evil that was before our eyes.
The public needs to know the truth and deal with it as a collective.
Their excuses will fade at that moment.
