Folks, many of the higher-priced items used by local law enforcement are paid for by DHS funds. The Colorado Springs Police Department's mobile command post, for example. A rather pricey chemical analyzer. S.W.A.T.'s tactical vehicle. All are required to sport the "Paid for by DHS funds" sticker, and they do.
In the meantime, DHS also buys stuff for use by the military, including the MRAPs, as well as a lot of the ammunition used by federal law-enforcement, who do use the 40 S&W JHP rounds.
So, let's look at this rationally and put the conspiratorial malarky on the back burner where it belongs.
