"And it came to pass that Bloomberg spoke.  And the sheep people listened.  And they believed him because they are as stupid ignorant as he is..."

In my opinion Bloomberg shouldn't be handling that, or any other, firearm.  He looks dangerous and more than a little incompetent.  He called it a "semi-automatic machine gun".  Who knows what mayhem he is capable of....

Stay safe.
