Are they bulletproof??

I received a link to this article from Police Link, which I guess at one time I subscribed to out of sheer frustration and need to connect on any level. Well, a few days back I was rewarded with this hilarious article. Well, the article isn't necessarily hilarious but the title of it is:

Sheriff's Office Fighting High Crime Areas With Sumo Suits

What's your first thought? Of course mine, as mentioned in the title, is "Are those sumo suits bulletproof? Probably not the best outfit for undercover work, but, ok..." Hope you get a good laugh like I did out of the inconsequential.
