This has everything to do with demographics and science that presents findings contrary to ideology/politics. The same kinds of people pressure police to omit demographics data in police reports.
Interestingly, the article states that the data sharing agreements do not limit what the researchers can publish. They can share results/conclusions critical of the state, which could then serve as a basis for litigation.
What's weird is that they are being prevented from voluntary testimony on cases unrelated to the specific shared data, thus unnecessarily removing many experts from the pool.
