According to Mathias Ståhle, the weapons used in the shootings often come from former war zones, such as the former Yugoslavia.
But since a few years ago, another type of weapon has also flourished.
- Weapons that are rebuilt in illegal weapons forges in Sweden, including in Sörmland, he says.
Replicas are being rebuilt
According to Mathias Ståhle, these are often replicas of real weapons that are not meant to be used with sharp ammunition.
Those who rebuild their weapons are often ordinary craftsmen who are far from the criminals who use the weapons in the end.
- The people we looked at are often in the countryside.
Many of them have a background as hunters or snipers.
Criticism from snipers
You have received some criticism from legal hunters and sport shooters who say that you are exaggerating the problem ...
- Yes, they feel suspicious, but they should not have to do them.
The problem is not that hunting and sport shooting exist because the vast majority of all hunters in Sweden are honest and polite.
In the clip, Mathias Ståhle tells more about where the weapons come from and what the chain looks like from the weapons forge to the criminal who presses the trigger.
