When I moved from the US to the UK, the use of quotation marks in news headlines was something that confused me. In the US, these would be "scare quote", with the quotation marks basically standing in for the words "so-called". In the UK, that is NOT their meaning. The quotation marks mean "we are not ourselves in a position to verify this, but it is the words that a source has told us". Very different meaning -- and once I got used to it, I think the UK use of language in this case is more honest and useful.
tl;dr: two countries, divided by a common language.
