The NRA does plenty of activism that doesn't involve defending people against charges, but for this incident they've been silent. For comparison, here is a statement that was put out by Gun Owners of America: https://www.gunowners.org/goa-speaks-out-after-no-knock-raid... . IMO it doesn't go far enough, condemning the general practice but failing to condemn the specific murderers, but at least they've said something.
