"a D.C. law that says gun manufacturers can be held accountable for violence from assault weapons."
What does it matter whether the gun you're shot with is an assault weapon, or a simple .45 revolver?
Nothing at all, except that the assailant that used the 45 will probably put just one hole in your body (likely into a vital organ, while the dummy with the assault weapon will probably miss you altogether, while wounding a slew of none targets.
If you are the target you want the assaliant to be using an assault weapon. If you are an innocent by-stander, you are safer when the shooter is using the 45.
Since they're also suing S&W, one has to assume that the 'simple .45 revolver' is now also considered an assault weapon.
And please don't call my .45 revolver 'simple', it's bright and shiny! (and a little out of focus)
Or a cross-bow, or a dart gun. Series, it is abolutely amazing how stoopid the anti-gun types are.
