Sadly, Hamas uses their hospitals to store weapons as well as schools and Mosque's. We have all seen the Palestinians use their ambulance's to transport weapons, supplies and terrorists from one location to another. So the idea that Hamas would cannibalize this equipment for some nefarious purpose should come as no shock to anybody! But given the PR nature of this issue Israel needs to explain what it fears the use would be. Then set up a verification process to systematically check the machines by a neutral unbiased group and make sure this has not and does not happen. The idea that Hamas perverts humanitarian aid as a cover to create more weapons or fortifications really shouldn't shock anybody and this overreaction for PR's sake is a silly as being "shocked, shocked that there's gambling going on in the casino". So save the hollow indignation against Israel.
