You are intentionally being obtuse if you don't see how a fingerprint database is "sensitive". The argument doesn't take practicality into consideration, potential bad actors just jumped from:

1) The government

2) Anybody who would go through the trouble of very noisily pulling all the scattered public data together

To:

1) Anybody

While I am of the opinion that any data held by a third part (to include the government) should be considered insecure, that doesn't blind me to the practical impact of a massive data dump.
