DHS Buying Bullets, Bulletproof Booths - What are they up to?

As if you need a rocket scientist to figure this out -

The Department of Homeland Security recently stoked concern by contracting a company to provide them with 450 million rounds of hollow point bullets. Now the federal agency is also purchasing bullet-proof checkpoint booths that include ‘stop and go’ lights.

A press release from Shelters Direct brags about how they are providing the DHS with bullet resistant guard booths. Images of the booth from the company’s website suggest the guard shacks will be used to control checkpoints.

Why would they do that? I wonder if that's ever happened before...

Funny, Americans like to play games where they shoot Nazis. I wonder if in a few decades the citizens will like to play games where they shoot Americans...
