Help find a home for this lost Washington.md data

This PR #745 required deleting this data. I don't know who was using it or what for. We can throw it away as far as I'm concered. But if it's useful, then it should be rolled into the specific case descriptions.

I think having OPA numbers would be valuable -- the investigations are being concluded with unusual speed (https://www.seattle.gov/opa/case-data/demonstration-complaint-dashboard; note that all the investigations listed above are on the dashboard) and it would be nice to be able to go back later and see which of these cases of misconduct result in actual officer discipline. But given that these descriptions often will not suffice to uniquely identify the incident in question, suggest that associating OPA number (if it ever gets done) will have to wait until reports are made public (which will happen once investigations are complete; that should be within 90 days of the complaint but could be much much sooner).

I agree with @ContributingThrowaway , there are probably a dozen incidents that match "Pepper spraying peaceful protestors" and "A confrontation between an officer and a male"

But once those reports come out, then maybe we could return. I thought we had an incident for the homeless man, but it must've been a homeless man gassed in some other city 🤦‍♀️
