As someone else already remarked, we are seeing the tip of the iceberg.
Look at the HIGH amount of success of prosecutions by the DA in SD.
Now, compare that to the number of missing children, dead children, the INTERNATIONAL CHILD PORN/RAPE ring run out of SD and totally UNKNOWN to the LE and DA until informed by A GROUP FROM "SWEDEN" (of all places) that were investigating CHILD PORN.
This is how the cases in SD seem to be run.
Police arrest someone, then they gather evidence used to convict them in court. LE's look good. DA looks good.
Problem is the guilty are still running the streets free killing and raping, while innocent people are stuck in prison.
This is just now starting to be seen by the ENTIRE NATION for what it is, due to the search for DANIELLE going NATIONWIDE!
