sentences:  In a 2001 study, Lott and John E. Whitley reported that safe-storage gun laws not only did not reduce juvenile suicides or accidental gun deaths, but that they also increased rates of violent and property crime.The study was criticized by Webster et al.in the "Journal of the American Medical Association" for using Tobit regression despite the fact that the data used in the study on youth suicides was "highly skewed and heteroskedastic", and because the vast majority of crimes that Lott and Whitley claimed increased due to safe-storage laws occurred outside the home.
