Clearly from what you posted it has been emotional for you. You posted: "German here... ever since we stopped being able to rely on the police we turned to making home made weapons for protection. You would be surprised how effective a sealed off pipe filled with scrap metal and gun powder can be." That's how puffed up Internet Tough Guys talk. Germans have lots of legal options for protecting themselves. That's why I asked you about kleinen Waffenschein. But you as Internet Tough Guy want to talk about building illegal weapons that go boom. Your remaining emotional appeal to distract from that is noted.
