Obviously, mitzvot that are broken publicly, or that are found out carried with them enforceable punishments -- such as execution for murder or adultery, or retribution for theft or usury. However, my question is this: was there any mechanism in Ancient Israel by which the laws related to one's own private life, such as taharat hamishpachah, or failure to abide by kosher laws, etc, were enforced? In many Islamic countries, we see "religious police" which police people's observance, often intruding into people's private lives to find where they fall short. Was there ever this kind of intrusion, or did the Sanhedrin/elders simply leave these sorts of things alone, knowing G-d would mete out justice Himself?
I know G-d sees the secret sins, that is not my question - it is whether or not there was some sort of state-sanctioned enforcement (or attempt at enforcement) of more "private" laxity in observance.
