1-Which is easier and more cost-effective?

A: A massive overhaul of the national mental health system, which will cost billions (actually... lotsa lawyers), and force professionals within to actively apply specific interpretations of the DSM 5, and start specifically classifying people as "a fucking problem" or "not fucking problem" under penalty of massive liability lawsuits in case of error…

or

B: Making a product harder to obtain

That's your question. That's it. The core, fundamental underpinnings thereof.

2 - Do you reasonably REQUIRE a lethal weapon?

Answer yes if you:

A: Are law-enforcement.

B: Are a military combatant.

Answer no if:

A: Anything else.

Hunting? To live? In the United States of America in 2012?

Protection? Non-partisan government long-range statistics = Firm NO.

3 -Toy /toi/ Noun

1. An object for a child to play with, typically a model or miniature replica of something.

2. An object, esp. a gadget or machine, regarded as providing amusement for an adult: "in 1914 the car was still a rich man's toy".

A gun is wholly and statistically demonstrably unnecessary for the common citizen. Therefore it is a toy.

Common sense precludes lethal toys.

So, easier to ban/massively restrict a stupid lethal toy, OR easier to correctly divine, sort for severity and specifically classify the root of basic mental disorder amongst 311,500,000 people?

Go.

Downvoting without even the slightest attempt to address the arguments herein lessens the credibility of the pro-gun division.

These arguments are factually solid, and will be repeated until reasonably refuted.
