I feel like you had additional context to this question that you meant to add, but just totally forgot.
As it stands, yes of course. If your house in condemned or otherwise subject to eminent domain, if your house is seized to pay creditors for non-mortgage debt (in some states), if somebody else has superior title to your home and you aren’t protected by being a bonafide purchaser, etc.

One issue from a legal/prosecutorial point of view (even assuming there is a willingness for the government to prosecute) is that the rules of evidence require authentication of documents. In the case of a whistleblower, they are themselves a witness and can authenticate (that is, attest to the genuine nature of) any supporting documents they bring in. If a whistleblower is killed, even if the government has the documents the whistleblower intended to authenticate, it becomes a lot trickier to use.
