This is why I proposed on [[Wikipedia talk:Bureaucrats]] that 'crats be given the authority to desysop/block in a wheel/edit war to defuse it and get discussion flowing again.
Sounds good - I like the idea of "desysop first, ask questions later". Asking questions can and should include reinstating admin powers in most cases. Preferably after the admin in question has agreed that they were in the wrong.
