Nonsense. This incident could have happened anywhere and is a situation faced by charter pilots daily all over the world. The UK (especially London) already has probably the most restrictive rules for flying over cities etc (with the possible exception of Canada). It really needs to be put in perspective - I've been flying around London since 1977-ish, and this is the first incident of its type. It's highly unlikely there will be any more.
This is possibly true. However, I read an interview with the crane driver that helicopters regularly flew below the height of the jib. So there is no room for complacency.
I just wonder what the reaction on Rotorheads would have been if the pilot had been a 500 hour PPL(H) and not a Skygod. Somewhat different, methinks.
