In May-June 1971, Malmer and Romare accompanied a delegation of experts sent by the international committee to investigate US crimes in Indochina and then reported on their experiences in 'Att samla några bevis'. The visual material is partly unique: it concerns, among other things, the documentation of the US Air Force's conscious investment in so-called anti-personnel bombs and mines. The use of napalm and chemical warfare agents is also discussed in a few sections, where an old woman and two mothers, who were in sprayed areas during their pregnancies, talk about and show the damage to themselves and their deformed children.
