already y e to c china or may soooon go to chchina. -t-the search h of the houoe confnfirmed he w was stealing infoformation, but we d didn't haveve the prf that he e was commititting esespionage, and

warrant. we told ththem what t they were u under arrese. thenen we transported themem o the e fbi officece to be proroc. -after f following s someone around foror two yearsrs and d getting toto know them withouout ever spepeaking to t, it makes t the first c conversan quitite an awkwaward one. jim gaylorord and gunnnnar newqt would d finally hehear from chc, his own n mouth, what his s story was.. -ok.k. -thihis one was s -- -and when jim asked d him ththe questionon about thehe , hehe was shockcked by it,, so he stararted muttering whatever he cocould think k f to d deflect frorom us. a great t moment iss when he e reads that tasking li, and hehe grabs foror a cup of tea thahat's been e empty for r 40 minuteses, anand he sucksks it to hisis h just to gigive him morore tie toto think abobout what hihis r is gonnana be. -hard d to explainin how you wd have such a a list in yoyour th and then to be typed in chinese. -very hard for chi to explain. we t thought we e had him. we really thought he wasas goig toto turn and talk t to us at that point, but hehe didn't. he dug h his feet inin, and itit was fruststrating. it was frurustrating 'cause w we knew --- wewe knew that he knew we had h. anand we all knew that he was lying, and he just refused to... refused to open up. whwhen i intererviewed chi mk fofor the secocond time withth omar lopepez, anotother ncis a agent, i'llll never fororget wawalking intoto the jail and chi wawaved at me.e. very unususual to seee chi mak k waving. i i really thohought that t thy our intervrview had enended twtwo eveningsgs earlier that he wowould neverr want t to talk to o me again. but ththat day, hehe waved, and he w wanted to t talk. so we e brought hihim in, and we dididn't reallyly have a a great plalan for how we wananted to talalk to chi. we just ststarted talklking tom about t the navy and uniteded states tetechnolo, and wewe built rapapport. -chi mak w wanted to b be the e smartest m man in the e . itit was realilized that c chk wanted to be "the professor."" and d so we, theherefore, haho puput ourselveves into a p posn of being t the studentnt in orr to getet chi mak to open up.. for chi i mak, ego was the e key to opepening him. -whehen we flattttered him about the work he e did, he wanteted to talk more aboutu. and d as he talklked more ababo, we talked d about the e signifie it wouould have toto china. anand we askeded, "did youou t to help ththe chinese?" he s said, "absosolutely." and ththen my respsponse was, "butut wouldn't t that also ht the e united statates navy?" and he e eventually y came arod and sasaid, "i gueuess you're e. i can'n't help chihina with nt hurtining the unitited states s" -well, for a lot of different reasosons. the first t reason was we werere doing itit at t the santa a ana prison. anand when we e went over r t, we never e expected hihim to t. and d it was notot ncis poliy to record all ofof our intererv. anand it just t wasn't ourur md of operaration. when chihi mak finally confesessed to mee thatat he had bebeen passing sensitivive informatation to ch, partrt of me wasas delighted. this w was a breakakthrough. ththis was somomething we'd been n working atat for a a long perioiod of tim, and now hehe was telliling the e truth. papart of me w was angry,, was pipissed, because hehe was puttiting sais intoto a really y vulnerable positition -- only to sasatisfy his s own e, onlyly to get ththe gratificicn ofof talking t to people about ththe work he e had don. he had no o regard for these e sailors' s safety and secucurity. -once e we made the arrest of chi mak and his family, then it wawas a waitining peri. and it wasn't until a year and a half laterr that we went to trail. but we were gonna dot every "i" and cross every "t" to make sure there were no gaps, nothing that could be taken advantage ofof to derailil the . because ththen i'd feeeel gui. feel guilt for letting these people get away withth what they did for d deca. -a defense contractor is now on trail. he's accccused of ststealing criticalal u.s. navyvy technoly for r the chinesese governmem. -the trailil went veryry smooty from o our end. we h had excellelent governmnt wiwitnesses anand special l matter expxpe, enengineers asas witnessess to whahat chi mak k was doin. and, of f course, a lot of a agents tookok the st, includuding myselflf, to tesestify aboutut what we'e'd seen anand what we'e'd recoverer. in the endnd, chi mak k was convnvicted of e every singlglee thatat was brougught againstst. -victoryry today fofor federal l prosecutoros as a formemer defensee induststry engineeeer, chi ma, was fofound guiltyty of conspspiring to e export u.s. defefense technhnology to communinist china.. -when chchi mak was s found guilty.... ...allll of the fafaith that w d to put intnto this invnvestigan frfrom the verery beginninig was s finally jujustified, finally y paid off.. -the cononviction ofof chi mk on all c charges by a jurury of his p peers was s extremely y satisfyingng . it wasas a huge wiwin for the whole e intelligenence bra. -once the decision had come out ththat chi wasas guilty of the chaharges, the rest o of the famimily came i in on a plelea deal. the mak k family was all chcharged togegether. all l pled guiltlty to agent of a fororeign goverernment, internatioional traffific and d arms regululations, consnspiracy, false ofofficial statatement. -chi m mak is currrrently servra 2424-plus yearar sentence e in . -the rest t of the famamily hahas served o out their s sene and have b been deportrted to c. chi got a a just sentetence, anand we learnrned a greatat l about the e chinese memethods ofof operationon. the mak cacase really y demonsts how w the chinesese used famay toto commit esespionage. in a f family, youou can truste anotother, you k know who ththe. it allowows them to o have nanatural relalationships.. bubut the resusults ofof our invesestigation isis we caughtht a familyy who wawas committiting espiona. we caught t a family o of spi. -thihis ended upup being a a milestone e case. itit showed ththat we could convnvict peoplele on thehese sorts o of charge. and d since thenen, acroross the couountry, we've e been ablee to sucuccessfully y charge anand prosecutute people for espipionage anand espionagage-type criri. -chi m mak stole sensitivive navy infnformatin and gave i it to the c chinee governmentnt for over r a deca. -the t technologyy that chihi mak gave e china significanantly reduceces the , ththe technolological gapp betweeeen the unitited states y and d the chinesese
