In the past the Brady Campaign has come out against so-called "plastic guns." Plastic guns are a theoretical weapon containing no metal parts, and so would be undetectable when passing through a metal detector. Gun rights group point out however that the technology does not exist to create these weapons, making the Brady Campaign's anti gun advocacy on this front spurious.
Sarah Brady, the head of the Brady Campaign when the Brady Bill named for her husband was passed by the Congress, attracted controversy for a gun she purchased for her son at a gun sale. Critics accuse this anti gun advocate of making a "straw" purchase.
A straw purchase is when a person who is able to pass a background check to purchase a gun buys a gun for an individual who would be prohibited from doing so. Sarah Brady's supporters, however claim that she did not violate the law because there is a provision allowing guns to be purchased for family members, as well as because her son is permitted to purchase guns in his own name.
