These are precision weapons. It's not like carpet bombing. Some bystanders might get caught in the blast, but that's not the objective. The objective is to take out strategic targets, and at the same time make all onlookers poop their pants. When they surrender, we'll give `em fresh undies.
I think Republican Guard's barracks count as a strategic target. Likewise many government buildings. And of course power stations, communications and the like. Don't be standing near any of those, and you'll be safe, at least by middle eastern standards.
The worst that can happen is Saddam jams the GPS signal, so they go a bit off course. And from what I gather, that's not likely to be very effective.
