The tabloid press has an obligation to check it's sources?! Yeah, and if a frog had wings it wouldn't bump its arse when it hopped! Good luck with that.But dont they have an obligation to check. If I call The Sun and say I have evidence that Wenger likes kids, and they go and print the story the next day, Im pretty certain they could be done for it.
But in any case, no, for something as completely mundane as saying people got drunk on holiday, they don't really need to check their sources as there is no comeback for it. The worst that could happen is a climb down.
Calling someone a paedo tends to cause more retaliation.
