Yes, they did a prison experiment. Split participants into prisoners and guards. Allowed the guards to conceal their identifies as well I believe (i.e. COVID masks). They had to stop the experiment early because the guards became sadistic and started physically and verbally abusing the prisoners. Or should I say, the guard participants were probably already sadistic and permission from an authority to let loose got them excited.

Almost as if these types of experiments were specifically run to gather the necessary knowledge to carry out the COVID psyop.
