Why the heck should normal citiziens run around with (half) automatic assault rifles ( thats the correct translation i believe)?
They are designed to kill as much people as possible in the shortest timeframe.
You have propaganda on the brain but thankfully ask questions that will reveal the logical errors which are always in propaganda.
The word is "semi-automatic." Regarding the bolded, that is inaccurate. Let me please explain something.
For the past 100 years or longer, yesterday's military weapon becomes today's hunting or personal protection weapon.
I believe most people would agree, AR15 variations are the most popular in the world for hunting, personal protection and so forth. AK47 I don't know of it's use for hunting, but it could be in the West we don't hear of that, we only see it's use by "enemies."
Please learn about these things before voicing strong opinion as to what is "right."
Also note many things are illegal for average citizen - silencers, rifle barrels shorter than 14", machine gun, etc. etc. In the USA some states have tried banning magazines with capacity higher than 10 rounds. Those efforts I believe, everyone agrees have been failures.
