Los Angeles - A majority of US teenagers say they have used violence in the past year, and one in five high-school-age boys took a weapon to school, according to a new survey conducted by the California-based Institute of Ethics.
The random survey, conducted last year among more than 15,000 teenagers at schools nation-wide, showed that 75 per cent of boys and 60 per cent of girls said they had hit someone out of anger in the past year.
