Also, exec order has very limited and strict rules. Making up new laws and circumventing an existing one is not within those powers. Anything limited the 2nd amendment in an exec order holds no legal water. Good for Rand Paul for seeing this.
I'm not sure what Rand Paul is saving us from at this point in time. None of the executive orders deal with gun control in the sense of taking away guns, or even immediately altering legislation. The only executive orders that even mention guns consist of issuing Presidential memorandums, improving incentive for states to share information for the background check system, directing the Attorney General to review categories of people prevented from owning guns, etc.
Nothing that the President said about assault rifles or high capacity magazines was included in any of the 23 executive orders, and the President himself said that such suggestions would need to be addressed by Congress, not executive order. I don't see anything within any of the executive orders that takes away any guns or immediately makes any changes.
Congrats to Rand Paul for realizing that such suggestions have to be passed by Congress, but that was already mentioned expressly by Obama during his speech.
