I don't know enough about German gun laws to try to meddle in your affairs and tell you how to do things.
That's strange, since you make the claim the government is "tyrannical" based on these same laws that you don't know about. That's a very strong and offensive claim to make by the way, as is accusing us of being sheep. I am trying to be calm and not react in kind but I admit it is hard with the insulting language you are using.
Here's some basic info, it discusses the kind of debate that's happening here recently:
Germany Faces Few Mass Shootings Amid Tough Gun Laws (Published 2015)
Germany has had a couple more mass shootings than the UK in recent years, and has a slightly higher rate of gun homicide, though still very low. After the Dunblane massacre in the UK in 1996 (a shooting in a primary school), gun laws became tighter to outlaw most handguns, and since then the UK has had a total of 1 mass shooting. In 20 years.

Self-defence against violent criminals is not something I spend my days thinking about, in the UK or in Germany or in Italy or in Austria... (I've lived in quite a few places, I admit it's confusing). To me it's a really great thing that I can afford not to think about violent gun crime. Yes, I'm small and female and unable to physically fight should someone stronger choose to attack me. But I honestly don't think owning a gun would help me in the slightest, especially since when recently someone tried to assault me I pretty much froze up in shock (and unless I'd been carrying the gun around on my person all day, it wouldn't have been to hand anyway, even though this happened in the house I was staying). That was in Serbia, another country that I lived in briefly which has far looser gun laws than the other places I've mentioned. I can say for certain I didn't feel any safer for that fact, quite the opposite.
I also don't believe I ever have a "right" to hurt or kill someone. It may be justified if I have
very good reason to believe they wish me serious harm and there is no other option like just running away. But even then I doubt I could actually go through with it.
We don't want to arm the ordinary police in the UK because for most people the threat of possible police brutality is much more real and present than the threat of violent criminals. There are special "firearms officers" who do carry guns, but they don't even turn up when there's rioting. We're talking "murderous gunman on the loose" before we see them in action normally. (This happened once, a fair few years ago, and was a rare enough event to get wall-to-wall coverage; I recall seeing armed police on the TV).
EDIT: I should be more clear here, actually this varies slightly between England and Wales, Scotland, and Northern Ireland, as there is some difference in the way these regions are policed.
My main point was, you cannot criticise my government or my country's laws and then turn round and object if your own country's laws are under discussion. You were happy to criticise Japanese bike registration and German noise regulation in another thread. This "if you don't like it, don't come here!" attitude is what I took issue with.
