2014年4月24日，吕某向单位请了假，准备飞赴重庆参加大学同学毕业十周年聚会。在杭州萧山国际机场，即将登机的他被机场公安带到了问询室，余杭公安随后将其带走调查。起初他还以为警察抓哪个同名同姓的逃犯搞错了。

  吕还向警方表明自己在政府法制部门工作。不过当警方提示他是否近期在网上买过枪，吕的“当时脑子‘轰’的一下完全反应不过来了。”因为他确实买过两支仿真枪。在被带回警局的12小时里，吕某交代了自己从网上购买仿真枪的事实，涉案的两支“仿真枪”也在当日被警方在吕的家中收缴，一同缴获的还有一盒塑料珠子弹。警方为他办理了取保候审。取保候审后的第一天起，吕就被单位停职了。

  一些亲朋好友间的传言也令吕某尴尬，有人说他是在机场携带了枪支被当场缴获。吕某系某重点大学环境资源保护法硕士研究生，在学校就入了党。毕业后，他回到浙江省某县法院，通过了司法考试，先后在办公室、民二庭、执行局工作，后调至政府法制部门工作，任副科长，获得诸多奖励。

   两支仿真枪的比动能为8.5焦耳/平方厘米、7焦耳/平方厘米，吕某被杭州中院以非法买卖枪支罪判处有期徒刑三年缓刑三年。按照规定，一审判决若生效吕某被开除党籍公职，前数十年的努力将白费。为此，我们代理二审，经多方努力，浙江高院于2016年4月18日改判免予处罚，总算保住了前程。

Former judge gets free sentence for buying 2 BB guns

One day in April 2014, Lu, a deputy section chief of the legal affairs office of a county government in Zhejiang province, was arrested by the police as he was boarding a flight to attend a classmate's party.

 Lu questioned whether the police made a mistake in the object, the police asked whether he bought "gun" on line.

Lu, a master's student in law at a key university, joined the Communist Party of China at school. After graduation, He passed the judicial examination and was transferred to the legal department as deputy section chief in a county court.The specific kinetic energy of the two BB guns was identified as 8.5 joules/cm² and 7 joules/cm².

 Lu  was later sentenced to three years imprisonment suspended for three years by Hangzhou Intermediate People's Court for illegally buying and selling guns. If the ruling stands, Lu will be expelled from the Communist Party of China and barred from legal work.After our intervention in the second trial, we pleaded not guilty. After many efforts, Zhejiang High People's Court changed the judgment and exempted he from punishment on April 18, 2016.

   The effective defense of similar cases not only restored nearly 200 years of freedom, but also created the conditions for the Supreme People's Court and The Supreme People's Procuratorate to issue new regulations on low-specific kinetic energy gun cases in March 2018.
