The report’s author had acknowledged that many of these activities are well intentioned and help fight crime and terrorism. But excessive use can create a climate of suspicion, they say.

wmt1708

报道的作者承认行动中相当多的一部分有良好的意愿，并且在和与犯罪和恐怖主义做斗争中的过程中起到了帮助。但过分的采取这些行动会使人们对这些行动的目的引起普遍的怀疑。  

they say中的they指的是“大众”吧？
