because he already checked them. watch as he leans over this stack of tickets. investigators say he's removing a tiny bit of the layer of the ticket. he's looking for the three-digit code. that code, plus the bar code, tells him it's a winner. he sells the losers to unsuspecting customers. the crime is called pinning because the cheater uses something small and sharp, like a pin. he scrapes a thin line on the ticket, where he knows he can see this three-digit code. that tells him what the tickets were. even frequent players can be fooled. unless you look closely, you'd never notice the small line of missing latex. >> there's millions of dollars at stake out there. >> reporter: the lottery has its own police. >> i look at this as stealing. >> reporter: that's because the lottery paid $1 billion to california schools last year. police say they investigate to keep the games fair and honest so you keep playing. >> we have looked at every, single scam that comes our way. >> reporter: which leads us back to this guy. police say theyot a tip he was selling scratchers that didn't look quite right. when they pulled the store video, they found it why. they said the clerk pinned ticket after ticket. investigators say he kept the pinned tickets in a drawer. watch as he pulls a bait and switch on the woman in the blue jacket. he picks up a set of valid tickets with his left hand. but in his right, he takes a pin ticket from the drawer. he pretends to fold and rip a new scratcher. but instead, sells her the pinned ticket, which he knows is already a loser. he does it again here, pretending to rip a new ticket. but selling a pinned ticket from his drawer instead. investigators say they caught him on tape selling three pinned ticket. and they confiscated 50 more. his own video contributed to his arrest? >> absolutely. >> reporter: how dumb are these guys? >> sometimes they don't think. >> reporter: after police arrested this clerk, they yanked his lottery contract and the store shut down. in other pinning cases, suspects tried to cover their tracks with whiteout, literally, pointing over the layer they scraped off. and that works? >> most of us believe that the lottery product they're getting is solid. >> reporter: to make sure the game stays solid, investigators go undercover, with a decoy scratcher worth $10,000. at this san jose store, the clerk tells the undercover officer, it's not a winner. neither are good?
