1. It's not clear what that expression actually means; how is the population of Gaza used as "human shields"?

2. Even if it was true, does that then justify murdering them? When there is hostage taking in, say, a supermarket the police tries their best to stop only the hostage taker(s) and not their victim(s); they certainly don't bomb the entire supermarket from the sky causing 500 casualties.

Many Western countries have had brutal acts of terrors committed against them, they didn't raze the entire neighborhoods were the perpetrators lived.

We're talking about Israel intentionally killing their own hostages, right?
