“There are more than 10 million AR-15 and AK-47s on the streets of our communities today and so we must take the necessary though politically difficult step of saying that we have to buy those AR-15 and AK-47s,” O’Rourke said. “This is a mandate that every single American who owns one of them will have to fulfill.”

Beto, please be truthful with the American people.  When you say “buy back” you really mean “confiscate.”  

When you say “mandate” you mean that “I, Beto O’Rourke, will make it mandatory once I am president of the U.S. for all Americans who own an AR 15 to turn them over to the government.”  I don’t know what “mandate” you are talking about; and you have not been given a mandate to do any such thing. 

We are not deceived by your self-arrogating and misleading language.

I come from a country whose leader agrees with you: “armas para que?” (“who needs firearms?”).  

That leader was FIDEL CASTRO.
