You clearly know little about Uzi’s.
They come in three sizes, different rates of fire, and several calibers.
The kid should have been able to handle a full size, or even a Mini in 9-mm.
The Micro is the most difficult (and fastest rate of fire) to handle in FA, and not one I would have allowed him to shoot in 9-mm, but might in .22 if he appeared reasonably strong coordinated.
I’ve made a lot of kids VERY happy shooting several models of my machine guns, including Full Size UZI, no one has ever gotten so much as a scratch.
I’ve done this for several years at many events.
We always either hold the kid in a supporting manner, or are nearly doing so. For at least for the first mag, until they demonstrate that they have no trouble controlling the firearm.
The most common error of new shooters is to lean BACK instead of forward into the recoil.
That can be unstable for slightly built women and kids.
From what I have read the Micro got away from him, a tragic error was made, but there was clearly no criminal INTENT.
Remember the principle of criminal INTENT?
Apparently the jury does.
You obviously know nothing about children, gun safety or the law.
Criminal intent is NOT required in negligent or reckless homicide cases.
No 8 year old should ever fire any automatic weapon, period. Even if you disagree with that, the fact that the boy was killed clearly proves that in this case it was done in an unsafe manner.
