Is Prince still a Jehovah 's wittiness or is he now excommunicated.?

I dont know but I was reading in a JW form that Prince was no longer a JW and was excommunicated for questioning the doctine of 1914,after seaching history he now knows Jerusalem fell in 586 not 606 or 607, which would destroy this doctine. 2nd he question the prophecies which the WTS addmits in the Awake oct-8-1968 pg23 "those"mean C.T.RUSSELL AND RUTHERFORD. HE was exed for examaning the teachings of the WTS, but does not the WTS say to everyone "examin your religion but let there people examin the teachings of the WTS? I wonder why????????
