Others, however, criticized the study, saying its conclusions were reached by using flawed methodology and did not take into account other laws that made guns more difficult to obtain for felons. The study was conducted by University of Chicago Law School professor John Lott and David B. Mustard, a graduate student at the university's Department of Economics. It was presented at the Cato Institute in Washington. Lott and Mustard studied county-level crime statistics from around the United States, both in counties that had ``right to carry'' laws and in those that did not. They found that when state concealed handgun laws went into effect, murders fell by an average of 8.5 percent, while rapes and aggravated assaults fell on average by 5 percent and 7 pecent, respectively. ``The net effect of allowing concealed handguns is clearly to save lives,'' Lott wrote in the report. ``Allowing citizens without criminal records or histories of significant mental illness to carry concealed handguns deters violent crimes and appears to produce an extremely small and statistically insignificant change in accidental deaths.'' The study contradicts many earlier studies suggesting concealed weapon laws produced increased crime rates. Lott and Mustard used data from counties with concealed handgun laws from 1977 to 1992. They contend that states that do not have such laws could have prevented approximately 1,570 murders, 4,177 rapes and more than 60,000 aggravated assaults per year if such laws had been established in 1992. The authors also claimed that in localities where the public is allowed to carry concealed weapons, criminals turn to burglary and other types of crime that do not involve physcial confrontation. Lott and Mustard's study was roundly criticized by anti-handgun violence groups. One such criticism came from the Johns Hopkins Center for Gun Policy and Research, which said the study's findings were ``unsubstantiated'' and contained ``factual and methodological flaws.'' School officials said Lott and Mustard did not account for the effects of laws that make it more difficult for felons to obtain guns. They said the pair also used ``incorrect and discredited'' methodology, specifically, using arrest rates to predict crime rates. They said that high-crime areas that experienced a crime decline after introduction of the law may have seen the decline simply because of a drift toward a lower, long-term average level. Critics said the study also ignores long-established facts about the crimes of murder, rape and aggravated assault. Statistics have long shown such crimes usually occur between people who are related or who already know each other, a situation in which carrying a gun in public would have little relevance.
