一卓

清晨天未大亮，伴随着朦胧晨光和钥匙声响，马怀龙开始了一天的工作。今年57岁的马怀龙，2008年从部队转业到地方，成为青岛市公安局市北分局兴隆路派出所的一名社区民警。

马怀龙腰间的挎包里常年揣着46把钥匙，这是社区里的困难家庭自愿托付给他保管的。拎起这串沉甸甸的钥匙，金属碰撞的声音，诉说着其背后的故事。

马怀龙的第一把钥匙来自社区的一户残疾人家庭。2011年10月，马怀龙在走访入户时发现，男主人杜盛昌由于糖尿病并发症双腿溃烂，却没钱就医。马怀龙当即将他送往医院，与同事们一起为他捐款治疗。住院陪护期间，杜盛昌的妻子宋月兰将家里钥匙交给了马怀龙，方便其照顾独自在家的孩子，而这一帮就持续了十几年。

此后，凭着真心和爱心，马怀龙受到更多辖区居民的信任，他们主动将钥匙交给马怀龙保管，方便他随时登门看望。这些钥匙颜色样式各不相同，马怀龙都一一做了标记，不止标记在钥匙表面，更标记在他的心里。因为这些钥匙经常会被拿出来用，有的甚至每天都能用到，所以马怀龙对每一把钥匙都很熟悉。

46把钥匙，一共重798克。马怀龙每天拿着它们在社区里忙活，很多居民问他：“累么？”马怀龙的答案是：“不累，但是很沉。”对马怀龙来说，这些钥匙是责任、是信任。马怀龙16年如一日亲民、爱民、助民的感人事迹在青岛广泛传颂，也默默影响着他身边的人，这些人围绕在马怀龙身边，做着和马怀龙一样的事情。

辖区社会工作者、社会爱心人士、曾经受到马怀龙帮扶的人，主动和马怀龙一起照顾辖区孤残老人、帮扶困难群众。随着队伍的逐渐壮大，“马怀龙金盾志愿服務队”成立，目前共有360余名志愿者。他们中有专业的律师团队，为困难家庭提供法律援助；有专业的医护人员团队，为生病的困难群众提供上门救助；有专业的心理咨询师，为有精神疾病、心理问题的困难群众提供心理疏导；有人民教师，辅助一些困难家庭的孩子学习；也有理发师，按期给老人理发。在志愿服务活动的影响感召下，越来越多的爱心企业、爱心人士加入这支队伍，大家共同奉献爱心，汇集智慧力量，让困难群众感受到社会温暖。

一把钥匙，一份承诺。16年来，从马怀龙一个人的“一团火”，到志愿服务队的“满天星”，马怀龙敲开了困难家庭的房门，更打开了百姓的心门，生动践行了“人民公安为人民”的时代担当和庄严承诺。
