mrs. hoke may have placed in her own house, she was absolutely entitled to do so. i put jonas through college and grad school. gail... i waited tables. i did anything i could, because i believed we had a future together. do you have any idea what it's like to have your husband tell you your contribution to your marriage isn't of value? attorney: i think we should take a break now. i'm not finished with your client, counselor. you can't prove gail did anything. all i need to make out conspiracy at this point is probable cause. and your boyfriend's alarm system gives me exactly that. it also puts you in possession of material evidence, and an obstruction of justice charge, counselor. if jonas were a doctor or a lawyer, i'd be entitled to half of everything. but everything he had was inside his head, so tell me, agent sinclair, how do you get half of that? which is why you put surveillance in his house-- to see what was on his computer. it was the only way jonas would have ever given me what i was entitled to. right. but after you had the information you needed, why'd you kill him?

i didn't kill him. i could never do anything like that. i told you, he was late with a check. i went there to get it. that's when i found him dead. gail did not kill her husband. david: forgive me if i'm not willing to take your word for it. attorney: you don't have to. i have the surveillance, remember? so is this an audio file? no, actually, digital video. so the device was a camera? not exactly... it was an antenna. charlie: a van eck phreak. but at a far more sophisticated level. wait, what are you guys talking about? the wire you found in his house wasn't for a camera. it wasn't for a microphone. it was for a high-gain antenna. an antenna? for what? to pick up what? well, with any lcd screen, liquid crystals provide an image when energy passes through them. the color they become depends on the amount of energy that they're exposed to. when the energy passes through these liquid crystals, it emits a wave of electromagnetic radiation.

dutch physicist van eck realized that with an antenna and a decoder, you could both read the waves and decode them into a perfect replica of what someone would be seeing on their computer screen. what you're saying is that the antenna was able to read and pick up whatever was on hoke's home computer screen. that's right. that is amazing. hoke had elaborate safeguards against conventional hacking. firewalls, blockers... still, nothing could stop this. isn't that around the time he was killed? yeah. that's where the files were being erased. see the zeroes and ones just flipping around, back and forth? so the killer knew hoke's passwords. too bad he didn't leave a fingerprint. actually, you know what? i think he did. don: all right, so what are we looking at? digital representations of a pattern of keystrokes. one taken from hoke's computer at home, one from hoke's computer at work. now, you know that experts can distinguish one person's typing from another by their rhythm.

yeah, you mean like morse code. right. telegraph operators used to recognize each other by the different ways they used to tap into the exact same codes, like a concert pianist sitting down to play a piece of music. even though the notes originate from the sheet music, the way she plays them is entirely distinctive. now, if another pianist sits down to play the same piece of music, the strength of notes, the flourishes in rhythm would make the keystrokes totally different. now, only by seeing them side-by-side would you be able to tell they were different. see... now, i'm sitting here, and i'm looking at these, and they look identical to me. that's because they are, don. this is from hoke's computer at home. the keystrokes you're seeing are passwords used to tap into hoke's sabermetrics files, made after hoke was dead. this is from hoke's computer workstation at the lorman group, made after hoke was dead. so then this is the same person

that erased the files? don: scott reynolds, you're under arrest for the murder of dr. jonas hoke. get your hands up. ( handcuffs snap ) you have the right to remain silent. anything you say can and will be used against you in a court of law. bring him down. agent: all right, sir. go ahead. what do you want? i'm trying to figure out how you could kill a man, how you could kill a fellow scientist, to steal his work.

is that why you think i killed dr. hoke? for the money? you weren't jealous of his accomplishments. his accomplishments... is that what you call them? i grew up in west oakland. anyone i grew up with who isn't dead or in prison is flipping burgers or driving a truck. and it's not too difficult to guess what dr. hoke's formula would have said about putting a computer lab in my high school. that computer lab saved my life, and next year, it's gonna save somebody else's. and killing dr. hoke accomplishes that? you think it stops there? in the last century, the nazis used the theory of eugenics to stop the poor from reproducing. eventually, they justified just killing the sick ones. you can't compare that to this... actually, that's a perfect comparison, cause what jonas was doing was taking away a person's chance at life. it's taking away someone's hope. and i did what i had to do to stop that before it started.

that makes you a murderer. don't you ever wonder about your own work? what about my work? well, you consult for the nsa, don't you? ah... of course you do. so you're gonna tell me that everything you do will be used for good all the time? what's your point? well, you're asking me how i'm gonna live with myself. look in the mirror. ask yourself the same question. let's go. jonas hoke's last hurdle. oh, yes, his equation seeking to predict a person's chance at success.

he never got to finish it. i thought maybe i'd give it a shot myself. why? to what end? this work is just a self-fulfilling prophecy. what do you mean? well, charles, if we use numbers to choose who among us gets opportunity, then by definition, those we haven't chosen don't. i mean, that's not science. well, it's not good science. it's like, every year college football chooses a national champion, but they use computers to determine which two teams play for the title. and every year, invariably, some team gets left off that believes, well, it could have won the game on the field if it had just been given the chance. i've always believed that it was my duty to develop mathematical tools, and someone else's to use them wisely.

could i have been wrong? the consequence of our understanding subatomic particles was a horrible bomb that transformed the world we live in and a source of energy, the basis of life-saving techniques, and an indispensable scientific tool. science... you know, science, not this, but real science, is discovery, charles. it's not invention. the truths are there, whether we find them or not. listen, i'm gonna grab a bite to eat. you want to come? okay. thank you.
