> hedge funds use dark pools to make non-public trades, ensure fund liquidity, equity, lie, cheat, steal; etc.

No one is using dark pools to "lie, cheat, steal, etc." Plenty of market participants (including retail) use dark pools for goals like price improvement or sophisticated order handling like TWAP orders. Dark pools would not be possible without the lit markets that we all know and enjoy. All of these dark pool executions are reported to FINRA.
