Don't say we didn't warn ya, but now the long-anticipated plan for armed TSA agents to patrol U.S. cities has been invoked by none other than Jesse Jackson. Today he called on President Obama to unleash "Homeland Security" on the streets of Chicago, a city racked by murders and violence even though it has the strictest gun laws in the country. The only group within DHS that has the manpower to "occupy" a U.S. city is the TSA, a widely-hated government agency which has already begun running roadside checkpoints across the country.
