Oh dear. It sounds like many people's fears as to how well or otherwise the shoot would be hosted are coming true; not a great advert for FT :-(
It would be easy to say the WFTF should have practices & processes in place to avoid such but without being 'on the ground' it's hard to say. All you can do is stay frosty & shoot each target as it comes mate. Don't let it get to you, afterall you & the other Brit's have travelled a very long way at great expense for this!
