certainly regrettable, correct teaching technique would have placed the instructor/range officer behind the shooter, so the weapon could have been controlled by simply pushing the appropriate shoulder away from the no fire zone.
uzi's,
H@K, Mac 10, Thomsons etc. in the US are not submachine guns, a submachine gun is a select fire weapon and tightly controlled by the government, available but must have a tax stamp from the BTAF. These are no different than any other carbine, but of course the name has implications. Young folk are taught to shoot in the US before the mind control people get to them, I was taught at the age of six in the Boy Scouts.
Don't feel bad the commentator in a CNN broadcast got called out for the same mistake, and also the Head of the BATF in a news broadcast on Friday didn't even know the difference, categorizing them in all in the "evil gun" category.
Apparently this instructor had a tax stamp and from the news report instructed the girl to fire one shot then a burst. The UZI by definition is a automatic, but can be select fire (what lay people call full auto). The bolt is extremely heavy about 3-4 lbs. and the slamming of it back into the frame causes the recoil. The gun shoots a 9mm pistol round, not a high power rifle round.
Several years ago a similar incident happened at the Knolls Hill Tennessee machine gun shoot.
Yes people get to together and shoot machine guns (Nancy Pelosi, Barry Obama, and Michael Bloomberg were all sent personal invitations, with the entry fee waived, but refused to come, can't imagine why) God what a country.
