Should be an interesting lawsuit. This definitely opens up discovery since the Capital police supposedly investigated the incident and said deadly force was justified. This should allow the plaintiffs access to the reports, planning, and any action prior to and after the incident.
Nancy may be $hitting bricks by the time this goes to trial. Expect a large settlement offer to keep things quiet.
Discovery is probably exactly what this is about.
That’s the only hope they have as a DC jury will acquit.
