The reasons why the USDA might desire to purchase submachine guns with 30-round capacity boggles the mind just a bit:
The U.S. Department of Agriculture, Office of Inspector General, located in Washington, DC, pursuant to the authority of FAR Part 13, has a requirement for the commerical acquisition of submachine guns, .40 Cal. S&W, ambidextrous safety, semi-automatic or 2 shot burts trigger group, Tritium night sights for front and rear, rails for attachment of flashlight (front under fore grip) and scope (top rear), stock-collapsilbe or folding, magazine - 30 rd. capacity, sling, light weight, and oversized trigger guard for gloved operation.
The USDA oversees the Supplemental Nutritional Assistance Program (SNAP), colloquially known as Food Stamps. According to recent figures, there are a lot of people on Food Stamps. Since these people are struggling to fund their own needs for basic sustenance, it is quite unlikely that they would be unable to locate the funds necessary to exercise their 2nd Amendment right to bear arms by purchasing weapons for their households...
...so perhaps the USDA intends to distribute the guns for free along with the Food Stamps? It wouldn't be the first time the feds stepped into the weapons distribution business.
Thankfully, these recipients of the government's largesse are very spirited and independently-minded folk as a general rule, so most certainly they would only use those weapons to protect their home and family and/or defend themselves from the tyranny of an overreaching state...
A ready-made militia who would be naturally inclined to support the government.
Look, I'm not saying this is what is happening, and I'm not a conspiracy-minded fellow. It is perfectly reasonable to try and discern the possible motives driving such a request. And since it is such a nonsensical proposition that the federal department overseeing farming should be inquiring about submachine guns, it is reasonable to consider nonsensical answers to the question.
And the mere fact that nonsense is in play is reason enough to recognize how this request by the USDA is separated from reality and should be opposed.
