visa policies madness?

Let's see if I get this right: taxpayers pay taxes to the government, government distributes money to art funding, funding is thus given to project involving 19 artists from Iraq for first major show of Iraqi artists in UK.

Then Government denies artists entry (after £10.000 of aforementioned funding - government money - paid by taxpayers- is already spend on flights, hotels and visa application fees..) because they can not prove a stable bank account - now get this: because same government helped blast Iraq infrastructure.. anyone awake (in government)? What a waste of money, and I don't mean the artist's work nor the Cornerhouse for curating such a show...
