Sorry, but this is more than a grain of sand. A press release of the MCSO said
Investigators learned that Hawaii Department of Health utilizes a coding system defined by the federal government to categorize and code the required information on all Birth Certificates registered by the state including those registered in 1961. This process involves writing specific number codes by hand and in pencil, placed next to relevant information contained on the birth certificate. The coding numbers seen on the Presidents LFBC are not consistent with the coding responses required by the federal government to match the information presented. The incorrect codes indicate that the Presidents LFBC has been altered or amended.The error makes them look like fools when the posse bases claims of fraud on a federal manual they claim is from 1961, and the manual turns to be from years after the date of the presented certificate.
It makes them look like they are either not doing the meticulous investigation that was claimed, or they are outright lying (but probably the first). It casts doubt on any correct information they may have (false but accurate, any one?) And yes, that makes them look like the tin foil hat brigade, and makes those that buy into their errors look bad as well. Sorry if you can't see that.
These guys have multiple separate indications of forgery just on the document alone. If one turns out to be explainable, it does not in any way mean that the report of forgery is false, or that the whole investigation is invalid. Sorry you can’t see that.
