Concert-goers were banned from taking umbrellas into an outdoor JLS concert - because they posed a health and safety risk
This clearly was not a health and safety issue in spite of the claims made by the organisers. If umbrellas really were a health and safety risk they would need to be banned in busy high streets and the like. The real issue was those at the front obscuring everyone else's view of the concert if they had umbrellas up. Appealing to the concertgoers' common sense and courtesy should have been enough.
