FBI data crawler
I have leads on childabusers and orthodontists. Everyone who goes to an orthodntist should be fully traced forwards and backwards.
These people should be tagged for any and all crime. Take this set of data and assess which hubs and routes the monetary transactions of any type flow through.
Shut these off. Follow how the money flows point a to b by turn off all the lights, wait, wait, wait, turn them back on. Assess where x dollars left and x dollars arrive. Investigate this tunnel.
