Alright, well in that case Mossad headquarters is in a densely-populated area of Tel Aviv. Is Israel using its population center as a 'human shield'? Is the entirety of Tel Aviv a legitimate military target now? After all, we don't know where command bunkers and arms caches could be hidden throughout the city...
Also, due to mandatory conscription, most Israelis (except those exempt) have served in some capacity in the IDF, making them affiliated with the military. If a Palestinian who is a former fighter of Hamas is a valid target, are all IDF veterans also valid targets? This would make up a significant portion of the population.
I think these are also 'double standards' too.
