Why Don’t the Injured Capitol Police Sue House Speaker Nancy Pelosi for Refusing National Guard Protection for J6?

Translate:

President Trump offered Nancy Pelosi (and D. C. mayor Muriel Bowser) for J6 to protect the Capitol up to 20,000 National Guard troops which they refused, their excuse that “the optics wouldn’t be good,” proving that the optics they wanted was the invasion with rioting, much instigated by such as Ray Epps (who “oddly” hasn’t been indicted), so shouldn’t the Capitol Police officers injured on J6 be suing Pelosi and Bowser for the damage done to them? Wouldn’t that be justice now denied?
