In that cert number "151 71 015396", the first group of digits "151" is the state code. See http://www.peoplefindernow.com/3adofals.htm

The second group "71" is the birth year. That's obvious.

The third group is "015396" which is the sequential serial number of the recording of the birth record in Hawaii in the year 1971. According to US Vital Stats 1971, page 259 (http://www.cdc.gov/nchs/data/vsus/nat71_1.pdf) there were 15838 births in Hawaii in 1971. If births were perfectly even day-by-day births on 12/21/1971 (Tuesday), the serial number would be in the range 14918-14960. The difference of 436, is variance due to a recording that occurred some days later as well as reflects variance in the births per day.

I think, you have found the real reason for the black out, the date doesn’t match BO’s birthyear.
