my goodness, the amount of disinformation in this thread is staggering.
this was not a child "let loose" with an automatic weapon to run around with as he pleases.
this is a controlled environment at a Gun-range (very much akin to those in Las Vegas that are so popular in GD) where people can pay money to have a blast with restricted weapons under the watchful eye of someone who knows what they're doing.
in this instance, blame lies (from what i can tell) with the person responsible for the session that the father & child were having, who should have either coached the kid better or decided that the weapon would be too much for the little one and given him something safer.
Looking further into this tragic accident with more detail a Micro-Uzi is a handful for a grown man let alone a child, lots of recoil and rapid fire rate. The owner of that fire arm should have known better, the range officer should have recognized this, and the father should have asked more questions.
IF YOU'RE NOT SURE HOW A FIREARM WORKS BEFORE YOU USE IT, ASK OR PUT IT DOWN!
This is pretty much correct. the range officer is legally responsible and should have intervened.
secondly, owning fully-automatic weapons in the united states is not "illegal" and so on,
this:
There's some circumstances under which civilians can own fully automatic weapons, but it's sufficiently rare that I doubt they'd be for sale at a gun show. I'm sure you must be able to go to places and fire fully automatic weapons in controlled conditions, though.
EDIT: Looks like semi-auto weapons in the video, so that's not the issue. The issue is whether such a young child should have been firing the weapon. I don't know the laws on that.
I'm also pretty sure that you can own all the automatic weapons you like, so long as they can't actually fire on full auto. Some rifles are sold with different fire selector configurations - the army version might do 1, 3 and full, while the civilian version will only do 1. I don't know if Uzi make civilian versions of their weapons, but it's possible.
EDIT: It turns out Uzi do make semi-auto weapons for civilian use.
Wiki link.
is all nonsense. in America, you can purchase a fully-automatic weapon freely if it was manufactured/imported before the Firearm Owners Protection Act, with it's Machine-Gun-Ban of May-19th, 1986. these weapons are known as "pre-ban" and command incredibly high prices.
(such as up to $20,000 for an M16, compared to $1000 for law enforcement to buy one direct from the manufacturer)
otherwise, acquiring an in-country restricted wepon simply involves a full background check, a few forms (you need to register the firearm fully with the ATF and so on) and you need to pay a $200 tax stamp, this takes between one to three months. these are federal restrictions, local state laws may apply.
The ATF has quite specific rules on what legally constitutes a machine gun or not. the very vast majority of firearms manufactured in the united states are not "machine guns" and cannot be easily converted to be either.
Importing is quite a bit more complex and is quite rare.
