i'd say no, it doesn't feel the same as putting weapons stockpiles in a school.
holy crap, i just tried to look up "israeli soldier suicide bus", and found the link to the wikipedia article on palestinian suicide bombings. like half of them regard bus stations. At this point I'd say the biggest qualitative difference is that it seems like it didn't matter whether or not the soldiers were on the bus at all, because that didn't seem to be the target. but those are from a while back before the borders were closed.
please give me a link to what you're talking about. I can't find any recent incidents.
