But I think it's important to recognize that for an evil person going after helpless people in a gun free zone, typical hunting long guns can be very dangerous. In some cases in crowded areas, the damage may have been worse with, for example, a 1960s pump shotgun and buckshot.
...
That's right, short-barreled pump-action shotguns are very dangerous, despite the fact that they are useless for hunting. Even more dangerous than any rifles. Long-barreled pump pumps are also under suspicion, because it is easy to make a pump sawn-off from them. Therefore, pump-action shotguns are simply prohibited in some European countries. Semi-automatic shotguns are less dangerous, because with a handicraft shortened barrel, they usually lose the ability to reload.
We have a requirement in the law that the total length of the weapon should not be less than 80 cm, and the length of the barrel should not be less than 50 cm, but these requirements did not prevent some incidents. As for the fashion for "tactics", in itself it seems harmless to me, but rather funny. But it is unsafe when, for the sake of this fashion, manufacturers and legislators distribute dangerous types of weapons - short-barreled, small-sized, automatic and cheap.
As for practical shooting, there was recently one case with a middle-aged maniac (not uncommon - not married, lived with his mother), engaged in practical shooting, he had an AKM-type carbine under 9 mm. But it seems that he was preparing for his terrorist act in this way, and was not interested in sports. But it wasn't a mass shooting, he tried to break into the FSB building, killed a policeman in the parking lot, and was himself shot by a sniper on duty under a video camera. That is, practical shooting is not a prerequisite for terrorism, please understand me correctly.
