The video is pretty funny and worth a watch (and kudos to the gentleman at the store for taping it!). But I think it’s really important to point out that, if you are ever visited by the FBI, for any reason, the best thing to do is to say absolutely nothing. Not a little bit, not a sentence or two — nothing.
I’m not saying this because of what the person in the video says (I actually can’t make out anything he says, because it has been dubbed over) but because it is always, without a doubt, the best way to protect your rights and the rights of those in your community. As a lawyer friend of mine noted, anything you say could be twisted against you: “If, for instance, this gentleman said he knew nothing but actually did, they could get him on lying to a federal officer. So, like the overdubbing says, just say you’re not interested in talking to them.”
