Builders wearing Camera's on thier Helmets

Saw this today walking past a building site, all of them wearing camera's, first time I've seen builders wear them, I assume it's to prevent fraudulent claims against them, lots of 'unseen accidents' do happen when walking past scaffholds etc. Will probably become standard in the industry.

Problem will be if a real accident occured to one of the builders, the reason why Michael Schumacher's head injury was so bad was because of the Go Pro camera on his Ski helmet, it hammered into him on impact, which is exactly what will happen to the builders if something heavy fall on their heads.

Seems inevitable imo.
