A law review by the Southern Methodist University of Dallas, Texas noted that: “PLCAA opponents... argue that the so-called "tidal wave of litigation" used to justify PLCAA's passage is exaggerated in terms of both scale and cost. They point to Congressional debates examining the SEC filings of gun giants like Smith & Wesson & Ruger. Rather than revealing the hundreds of millions of dollars in litigation costs purported to exist by PLCAA supporters, they expose multi-million dollar sales figures, but only de minimis legal expenses.
