Think about searching from the air for someone's head bobbing above the water only there's tens of thousands of approximately head sized/shaped objects floating in the water.
I think people just don't know what to say. In an event as big as this there had been no health and safety pre-report on possible...? no 'risk assesment'? Two deaths is two too many but thank God there were not more. So....stupid....pointless...wrong... ...naïve? 😢
