Ohio shooting of girl in Amish buggy a homicide

[rrneck]

31. Oooh. Let's look.

Mandatory locks
How will that be enforced? There are over 1.2 million NICS checks a month adding to an existing 300 million firearms. Prosecute after the firearm is found to be used in a crime? Fine. "I gave the combination to my roomate/boyfriend/girlfriend/house sitter/parent/adult child/uncle/aunt/cousin... need I go on? Regulating how something is stored and who has access to it amounts to regulating interpersonal relationships. How do you feel about same sex marriage?

limits on the number of firearms without special permit
Why? It only takes one to shoot somebody. Another impossible to define criteria designed to satisfy personal moral outrage.

mental health screening for all purchasers
Mental health screening is very expensive and time consuming. But I'll bet you're willing to make those buying the guns pay for it, right? That's called regulating something out of existence. But lets say you get your wish. Here's a history lesson:

http://en.wikipedia.org/wiki/Political_abuse_of_psychiatry
Political abuse of psychiatry is the purported misuse of psychiatric diagnosis, detention and treatment for the purposes of obstructing the fundamental human rights of certain groups and individuals in a society.[1][2]:491 In other words, abuse of psychiatry including one for political purposes is deliberate action of getting citizens certified, who, because of their mental condition, need neither psychiatric restraint nor psychiatric treatment.[3] Psychiatrists have been involved in human rights abuses in states across the world when the definitions of mental disease were expanded to include political disobedience.[4]:6 As scholars have long argued, governmental and medical institutions code menaces to authority as mental diseases during political disturbances.[5]:14 Nowadays, in many countries, political prisoners are sometimes confined and abused in mental institutions.[6]:3 Psychiatric confinement of sane people is uniformly considered[by whom?] a particularly pernicious form of repression

I suggest you get rid of that pesky second amendment first. And while you're at it, the fifth amendment. People have to be adjudicated mentally incompetent before they can be denied any constitutional right.

license required to buy ammunition
Useless without a gun. Why are you afraid to advocate licensing the purchase of guns? And if you got your wish for the guns, how efficient do you think it will be to track the movement of every gun made into perpetuity when a tiny fraction of them are used in crime, and a tiny fraction of those will leave a sufficient paper trail to be useful in prosecution? Now, multiply that by the billions or rounds of ammunition sold in this country every year and add to that the millions more that are made at home.

reinstatement of the assault weapons bans
You don't even know what an assault weapon is. How do you know what to ban?

limits on the number of buyers/resellers
You plan to accomplish that how? Please see above "regulating interpersonal relationships".

more oversight of current regulations
I assume you mean more effective use of current regulations. Not a bad idea. How do you plan to make that happen?
