A new poll shows that Americans generally support some of the most often-proposed limits on gun ownership, including universal background checks and banning semi-automatic weapons such as the AR-15. Americans broadly oppose a mandatory gun buyback program, do not want to ban handguns and do not believe gun manufacturers should be held liable when their products are later used in a crime. The first would require private sellers doing business at gun shows and over the internet to conduct background checks on buyers. The second would ban individuals who are on the government's terrorism watch list from purchasing guns, even if they have not been convicted of crimes. Proposals to reinstate a ban on semi-automatic weapons and to ban high-capacity magazines were favored by more than half of respondents and opposed by a quarter of them. Americans also broadly oppose efforts to make gun makers and sellers liable if a gun they produce or sell is used in a crime. Blacks and Hispanics were about evenly divided on the question, while a slim majority of Democrats say a weapon does more to put a person's safety at risk.
