cbs legal analyst rikki klieman is with us. good morning. how did google work with law enforcement?oogle has a policy and it says very clearly that it is going to look for evidence of child pornography. it's gone on the offensive about a year ago and said if we can find it, we're giving it to law enforcement. so what happens in this case it uses this algorithm, finds this image that appears to be child pornography, tells law enforcement. law enforcement then gets a search warrant. and lo and behold on the mobile device and on the tablet there are images of child pornography. >> so what exactly do they do to try to find it? >> it's a fascinating process, charlie. you know lots of law enforcement agencies throughout the country have been looking for algorithms that could help them out with things not only like child pornography but to identify chatter of terrorism and disturbances keywords. what google has is hashing. what this algorithm does it's actually like a fingerprint that it looks at a picture. and it can tell if a picture is of a child. and when it finds that it gives up the

rikki klieman is with us this morning. ase like this. do you think she has a case? >> i do think she has a case. and i think she has a case because the language of the policy that the city of florence kentucky has is just so basically overbroad. what they're saying anyone any city employee who is not getting injured are and getting a disability on the job, well we're not going to give you any kind of modified duty. we are not going to accommodate you. so i say when i look at this from a lawyer's perspective, that that's against the americans with disabilities act. let's take pregnancy out of the equation. and simply say, well if you get injured and you develop a disability at home that'squ recognized under the americans with disabilities act, well we can't put you on light duty. so on its face i say the policy won't work. then let's look at her situation. this is a situation where they're saying okay we'll going to let someone similarly situationed who is a pregnant woman come to work and go on modified duty. so on its face

rikki klieman is here this morning. we reached out to the governor's office, all the members of his commission, no one responded. why is the u.s. attorney involved here? >> well the u.s. attorney originally became involved because of the abrupt end of this commission. so the u.s. attorney says we're going to finish the commission's work. we're looking at corruption which was perfectly permissible for him to do. but that's months ago. so now this has escalated. why has it escalated? governor cuomo got his surrogates out there, the people who were on the commission to say, hey, this commission was fine. the governor the governor's people, they never bothered us we were independent. and the u.s. attorney said oh well isn't this intriguing. suddenly we have this onslaught of the governor's people saying this everything is fine so he took the bull by the horns. >> so does not suggest criminal witness tampering? >> well it certainly suggests the possibility of investigating criminal witness tampering as well as obstruction of
