Gallup: Most Americans practice charitable giving PRINCETON, N.J., Dec. 13 (UPI) -- The families of the victims of the mass shooting in Newtown, Conn., ask Americans to do something charitable to mark the one-year anniversary of the incident. A poll by Gallup found that most Americans are up to the task of doing something charitable to remember the 20 children and six educators who were killed by gunman Adam Lanza at Sandy Hook Elementary School on Dec. 14, 2012. About 65 percent of respondents volunteered their time to a religious organization or another charity in the past year, while 85 percent donated money, Gallup said. The poll, conducted Dec. 5-8, reached out to 1,031 adults nationwide. It has a margin of error of plus or minus four percentage points.
