Write Up Complexity of Finding Sentencing Data

### Background on the problem the feature will solve/improved user experience
Overall, we've done work on finding sentencing data. It varies by County, State, Federal. Sometimes race data isn't available, sometimes it is. Sometimes it's not accessible readily on websites, sometimes it is. We'd like a concise write up about our challenges to bring to attention of policy groups that could help draw attention to this. Without great data, we are going to be limited in where our solution can be used.

### Tasks
Complete a write up of our experience. Cite places that did well vs. places that could improve.

### Acceptance Criteria
Approval by Open Sentencing Team.

Revisa el trabajo existente del equipo para encontrar datos de sentencias en fuentes de condado, estatales y federales. Compara qué fuentes proporcionan datos sobre raza y son fácilmente accesibles, cita ejemplos de prácticas más sólidas y más débiles, y prepara un informe conciso para la aprobación del Open Sentencing Team.
