I've not followed up on the Pigford flap of 2 weeks ago. Based on links a reader graciously sent me, it seems that the rules for PC/internet usage generally follow those for the phone: personal use permitted on a limited basis, provided you use your common sense (work comes first, use during personal time, don't run businesses or distract co-workers).
So, is the woman in VA in trouble? Maybe, maybe not. Seems to depend on how close she came to lobbying Congress. My reading would say that, if she had gotten an email expressing a political opinion (for or against the war, etc.) she would be in her rights to send it on to a friend. Multiple addresses and more direct criticism of Congress would be questionable.
Will be interesting to see what the "independent investigator" appointed by Administrator Lasseter comes up with, and whether Congress buys it.
