This test is a total bullshit. The conclusion also bullshit.
"dass allein der Gasdruck aus einer Schreckschusswaffe tödliche Verletzungen hervorrufen kann"
No.
This test proved again: the legal gas-alarm guns are almost totally safe, even when fired from 10 centimers, no serious injury will hapen. Little dark coloration and small burns, nothing else.
If you are in contact distance, these devices CAN be lethal, IF you use them as a heavy metal hammer and break the skull.
