The German government has probably very little confidence in its citizens. Now they want to forbid the soft air weapons. Correctly, the plastic toy weapons.
As legend has it, somebody could modify soft air's to very dangerous weapons and they can cause heavy injuries.
They looked very authentic and they could be used for armed robberies.
I live close to Hamburg and therefore i take this city as example.
There is each day shootings with violated persons.
In the last years few hand grenades exploded in the city.
The owner of a discotheque didn't want to pay protection money to criminals. On one Saturday evening, when the discotheque was very full, the criminals threw a hand grenade in and injured some guests heavily.
The assassins of the 9/11 had their headquarter in the city.
I believe it give larger safety problems than toy weapons...
