There’s a YouTube video here with the discussion. Notice in the comments that “Jared” is rebutted by Hyperprapor and other Russians. They said that the media release (or propaganda) claiming that firearms could be carried for self-defense was a “media misconception.”
And remember that “self-defense weapons” there are have a limited light gas or powder charge and may only fire rubber bullets.
