Antipitas, I disagree with your opinion just a little bit.
Just because guns/ammunition would be outlawed, that would be solely for civilian possession. Military and police would probably pay what they have always paid for ammunition.
During the 94 AWB, military and police did not pay any more for standard capacity magazines, did they? Of course not, they continued to pay the normal prices. Do military and law enforcement pay outrageous amounts for full auto weapons? Of course not.
Why would their costs for ammunition be any different? Granted, ammunition companies would likely have a tough time, some probably going bankrupt or would have to move to producing other products to compensate.
The government never comes up with ways to make them pay more for anything. They find ways to make us pay more.
To answer the OP's question, well I would have to say that those who express outloud what they will do may find it more difficult to follow through than those who never express their answer to such questions. Watch out for the quiet ones.
