It would seem odd if such a major security change were implemented without some form of written directives for clarity and as a means of quality control
I don't know about written directives, but a fellow in my area who still talks to me mentioned that all the eldurrs and mistrial servants were called to a special meeting next state over. They had go through special training now to be attendants. No training=no more attendant duty. Something different is going on. And of course now they have another reason to feel "special" and just a bit better than the next JW.
