The advent of the ability of a sole defender to engage large numbers of assailants provides a stumbling block.
Due to the fact that, while rifles were used at the recent rash of mass atrocities, the hue is raised, however, in those cases, the perpetrator only used one magazine, then reverted to pistols, the favored one a Glock, establishes that none of the laws proposed would have prevented these. Only the knowledge that the assailant wil be beaten detters an assailant.
The solution is to face the fact that in every case, the existant government first deprived the victims of the ability of self- preservation. And now that same government plots to eliminate all private abilities.
