arraignment did not happen until 4 days after arrest
Your question doesn't make sense. 8/29/09 was a Thursday so the DA had 48 hours to arraign the defendant excluding weekends. 4 Days later was Monday or the last day for arraignment.
If you're saying that he was put in jail on 8/28 and was still in jail on 9/3 when he had his arraignment then, unless he waived time for arraignment it was probably against the law.
