That article appears to state that the use of human shields by Hamas is not true and fabricated by Israel.
It's not a term I've seen any real evidence for. If anything the opposite is true according to the linked and Guardian article. Israel is pursuing a policy of killing suspected members of Hamas in their family home/building when they are not engaged in warfare, using dumb bombs that guarantee there will be significant civilian casualties, likely in the low to high 10's and possibly higher.
How would that work? Is the IDF somehow forced to kill civilians? If so, how come the palestinian resistance groups aren't and considered accountable for it?
I think it is rather well documented.
