However, this claim contradicts the Southern Poverty Law Center, which states that the first incident of cooperation between the two movements was 6 months prior to these events on October 27, 1996, when the ALF & ELF were both responsible for firebombing a Forest Service truck in Detroit, Oregon.
可是，这一种断言同南方贫困法律中心的相抵触，它确定，两运动间的首次合作事件比这些早了6个月，在1996年10月27日，ALF与ELF都为向俄勒冈州底特律市一辆林业局的卡车投燃烧弹负责。
