I've happened to spend a couple of years with the Rebbe in American prison in the 90-s. You know, there you can't pretend, lie or misguide somebody for long. You see a man at the yard, in the sell, in the mess hall, in the bathroom, pardon. The most pious, G-d loving and righteous man I haven't seen. I thank G-d that I was given a chance in my live just to pass by and briefly touch the true Holiness. Shame on his detractors.
