<blockquote>The profane debasing of a mascot — and really anything that denigrates a team — is guaranteed to be contraband, said Daniel Modricker, a spokesman for US Immigration and Customs Enforcement. That “Yankees Suck” T-shirt you put on for special occasions? If it uses anything that looks like a team or league logo, it probably constitutes trademark infringement.</blockquote>

<blockquote>No, it really, really doesn't.  "Profane debasing"--and when did mascots become sacred?--is not confusing.  I don't think ICE has authority to seize diluting merchandise, and anyway very few of these will be using the profaned mascots "as a mark," meaning the dilution exceptions for parody and criticism apply. This is a blatant misunderstanding of the law, being perpetuated by a federal official with only the small reassurance that federal agents won't come down and rip a previously purchased shirt off your back.</blockquote>
