We don't leave it up to a religious fascist like Mike Johnson to chose who does or doesn't have rights. If a proper investigative body wants help identifying individuals, they can go through the proper procedures to release those images to ask the public for help identifying them. Which includes facing proper costs and consequences if any individuals are inappropriately identified by those efforts.
You're doing what the conservative SCOTUS justices always do when deleting our civil rights -- presuming the crime happened exactly as you believe it did then listing how bad it is in order to justify your conclusion that everyone involved should be drawn and quartered. It's an inversion of due process. Due process happens first, removal of rights second. If you have to remove rights first in order to have due process, there was no due process.
If you think it's a good point in general but don't agree in this case, I think you need to think about it a lot longer. Protecting rights is hard and sometimes requires letting some bad guys enjoy undue freedom. Privacy rights are under all-out assault right now and won't exist soon enough unless we follow rigorous, real principles around them.
