I've been following this on goinglikeelsie and KF.
goinglikeelsie tweeted: "After lunch, (not sure exact timing) JY's parent returns to hearing. Parent sits in back row of gallery, has taken off shoes and has bare feet (no socks) stuck through the back of seat ahead of them."
A KF poster says: "In India, feet are unclean, a sign of disrespect. Pointing the soles of your feet toward an Indian defendant is an act of deliberate racial hostility [....]"
Now, I don't know anything about feet being "unclean" in India, but I do remember seeing Iraqis hitting the downed statues of Saddam Hussein with their shoes, and it was explained that that was an act of great disrespect. So I can imagine the feet thing being a deliberate insult.
