this function does not actually call OnDidLoadRiskFingerprintData, so this
comment seems misleading to me. Perhaps:

Asks risk module to asynchronously load fingerprint data. Data will be returned
via OnDidLoadRiskFingerprintData.

and then you can remove the 2 lines between the 2 functions.

Done.
