The National Association of Chiefs of Police just released its 17th Annual Survey

Gun Control: With regard to private citizens owning firearms for sport or self-defense, 93.6 percent of the respondents supported civilian gun-ownership rights. Ninety-six percent of the police chiefs and sheriffs believe criminals obtain firearms from illegal sources and 92.2 percent revealed they hadn't arrested anyone for violation of the so-called "waiting period" laws. When asked if citizens concealed-weapons permits would reduce violent crime, 63.1 percent said yes.
