近来在香港“反送中”运动的示威活动中，警民冲突的状况一次比一次激烈。面对制暴及监视设备完善的警察，示威者除了穿戴保护物品以“防守”自身外，也逐步强化各种“出击”战术，透过雷射笔等各种道具，或者不同人员声东击西的模式，来分散警察的注意力，阻止搜证或遭暴力对待。

媒体报道指出，绿色雷射笔已成香港示威者的必备物品，他们会用以射向警察拍照、录影的镜头，或向镜头喷洒颜料及打开雨伞，防范警察拍摄其脸部。

对于示威者而言，分工合作也同样重要。在一组人负责利用上述工具干扰警察之际，另一组人指挥群众因应情势改变队形，第三组人则在后方呼喊口号，以凝聚示威气势，并且有负责侦察各区情况的跑者，四处传达最新讯息或传递供应品，其中不乏练过城市极限运动“跑酷”的人士。

10秒摧毁催泪弹

而一旦警方发射催泪弹，示威者会以4到5人为一组，有人负责持伞防御，有人先以交通三角锥盖住催泪弹，然后持水瓶往交通三角锥顶端的孔洞灌水，将交通锥拿开后，有人以烤肉夹把催泪弹丢入水桶中，整个过程仅花10秒。
