Perish the thought that they might wait until the facts of the accident are established before presenting their case.
If you lost your business premises, husband, father etc in a car accident that was no fault of you or them then would you wait until after the FAI in perhaps six months time before making a claim?
Presumably the people going to the lawyers are completely innocent parties so it does not seem fair to expect them to wait a year or so for the AAIB to complete their investigations before making a claim.
