I think this Julian Assange business is being portrayed as unnecessarily complicated. The crucial point is that there is a European arrest warrant out for him, and therefore if he leaves the Ecuadorean embassy we are bound to arrest him under the authority of that warrant, irrespective of what we may feel about the rights or wrongs of the situation.  The matter is therefore not of our making and not within our power to do anything about.
