When and why do citizens living amid criminal violence pour into the streets to demand peace and justice, regardless of the risks that protesting in such a context may entail? While victimization experiences provide an initial motivation for participation in protests, this article finds that social networks play a fundamental role for mobilization against insecurity. At an emotional level, socialization within networks helps transform the feelings of individual fear that crime evokes into collective anger that represents potential for action. As individuals become more engaged with one another, their feelings are transformed from being exclusively self-oriented towards other-oriented. Additionally, denser network interactions insulate participants from coercion and generate support mechanisms for their members, creating a sense of security. Thus, networks have the power to transform perceptions of the risks and effectiveness associated with their collective action against crime. Supporting evidence for this argument is derived from original survey data collected in Mexico in 2012. Additionally, in-depth interviews with protest participants reveal the mechanisms through which social networks stimulate protest participation, among both victims and non-victims. This article contributes to the prevailing literature on victimization and political participation and provides new answers on when and how experience with violence can encourage involvement in politics and promote democratic accountability.

生活在犯罪暴力中的公民何时以及为何涌上街头要求和平与正义，而不管在这种情况下抗议可能带来的风险？虽然受害经历为参与抗议提供了最初的动机，但本文发现社交网络在动员反对不安全感方面发挥着重要作用。在情感层面，网络内的社交有助于将犯罪引起的个人恐惧感转变为代表行动潜力的集体愤怒。随着个人变得更加相互参与，他们的感受从完全以自我为导向转变为以他人为导向。此外，更密集的网络交互使参与者免受胁迫，并为其成员生成支持机制，从而产生安全感。因此，网络有能力改变对与其集体打击犯罪行动相关的风险和有效性的认识。支持这一论点的证据来自 2012 年在墨西哥收集的原始调查数据。此外，对抗议参与者的深入采访揭示了社交网络刺激受害者和非受害者参与抗议的机制。本文为关于受害和政治参与的流行文献做出了贡献，并就暴力经验何时以及如何鼓励参与政治和促进民主问责提供了新的答案。支持这一论点的证据来自 2012 年在墨西哥收集的原始调查数据。此外，对抗议参与者的深入采访揭示了社交网络刺激受害者和非受害者参与抗议的机制。本文为关于受害和政治参与的流行文献做出了贡献，并就暴力经验何时以及如何鼓励参与政治和促进民主问责提供了新的答案。支持这一论点的证据来自 2012 年在墨西哥收集的原始调查数据。此外，对抗议参与者的深入采访揭示了社交网络刺激受害者和非受害者参与抗议的机制。本文为关于受害和政治参与的流行文献做出了贡献，并就暴力经验何时以及如何鼓励参与政治和促进民主问责提供了新的答案。
