Whatever the gobbier types on here think or do not think is irrelevant. You cant take short cuts and you cannot train anyone in 4 weeks. It would not satisfy certain authorities, otherwise, dont you think it would have been tried before? The course wasnt 18 months long for a laugh, whatever your previous trade was.
Besides this, I think we have serious thread drift because I dont think anyone in authority has admitted to a shortfall in manpower. (or have they ? )
