The 33-year-old also cut the judge off as he advised him of his rights."May 1, 1776," Colbert repeated at least three times.On Wednesday, Colbert allegedly fired several shots from his ex-girlfriend's apartment complex near West Kalmia and Brant Streets in the Bankers Hill neighborhood, narrowly missing an officer.He surrendered following a five-hour standoff. San Diego police Chief Shelley Zimmerman said authorities recovered an AK-47-type assault rifle and a handgun.
