I am a gun owner. Currently have around 30 or so. Many are SEMIautomatic. I don't own any of what are called assault weapons but all or most of my semiautos would be be banned under the proposed laws. What a crock of sh!t. I have a 22 semiauto rifle that I use to shoot racoons and foxes that are trying to kill my chickens. Many times they have died from the second, third, or even fourth shot. The gun control lobby think this type of weapon should be banned.
Also the news is now reporting the the "assault rifle" jammed and most of the shooting was done with the other weapons he carried. One of which, the Remington 870 (I own 2 of them) are pump action.
My take is that if a person is in a mindset to kill lots of people the type of weapons he has access to will not matter. Ban semiauto guns and they will carry multiple manual ones. Ban all guns and they will use a bomb of some sort. You can't legislate away the psycotic intent of the criminally insane.
