Obviously we should make sure psychopathic nuts can't buy weapons. I agree with that.
But, like any other seemingly "intelligent" view, limitation on who could purchase weapons has a high chance of leading up to an outright ban. It starts small and grows subtly.
And no, that is a very realistic, possible situation.
crimepreventionresearchcenter.…I recommend reading that link. Gun control allows criminals to feel more confident in their capabilities. Because, just like when alcohol was banned back during the Prohibition, people STILL participated in consuming it illegally.
If guns are limited, they will eventually be banned, which will lead to civilized people being killed faster than ever before.
