Dont even sweat this load of poo! The Dorner story is bullshit because he obtained them illegally, not with a trust of any kind. No one can have a suppressor outside of licensed FFL holders and they are restricted to doing demos for LE and Gov sales.
Unless that clown stole them, he did not obtain them with a trust. Just more liberal anti gun sewage that they are so commonly spitting out these days.
If you have a law office written trust, you are safe.
