They might have been revising the site to bring it more up to date. When I looked they had the break down for the older period, but not for the more up-to-date figures.

All the shots I've seen of this kind of thing on TV have looked very much less organised than that system troll mentions. Very similar indeed to Northern Ireland, where similar suggestions have sometimes being made.

Maybe there seem to be more rocks lying about to throw, because of the nature of the country; and the range at which the firing is done by the soldiers seems a fair bit longer than it does in similar scenes in Ireland, with live bullets being used at a distance which is further than stone throwing range.
