Force all government (federal and state) to purchase / contract USA made products that include vehicles and weapons

We as a country should not allow the Federal and state agencies to use our tax money to buy foreign vehicles, firearms, and other foreign products. Its embarrassing as a citizen of this great country to see police officers riding around on BMW motorcycles and watching military documentaries seeing our great military using foreign made weapons (heckler and koch). All of these agencies should be contracted to USA made products only and not "USA assembled" or any other foreign companies. I would like to see our tax money being put back into the American circulation.
