When Does the Right to Counsel Attach?

On Sunday I promised to post something on Rothgery v. Gillespie County, the Sixth Amendment Right to Counsel case that was argued yesterday.  However, in lieu of posting my own analysis  allow me to link to a very good short post by Orin Kerr at Volokh.  If you're at all interested in the question of when the constitutional right to counsel should attach or what the Supreme Court has said on that matter in the past you should give it a read.
