The U.S. Department of Homeland Security, whose mission is to protect us from terrorist attack and react to national disasters, was able to divert some manpower last month to the Bay Area to crack down on the sale of unlicensed Warriors gear.In a monthlong operation, Homeland Security agents seized 14,000 unlicensed items from street vendors.Couldn't the illegal-souvenir cleanup have been handled by lower-level defense forces, like school crossing guards who are idle for the summer?The Warriors won the NBA championship and their devoted fans want to celebrate by rocking Dubs' gear, but not everyone can pony up for the $35 T-shirts and $40 caps the team sells.Do your part, Warriors and other teams, to return our Homeland Security agents to anti-terrorist duty.
