>> hello. the data, we are told, is going to change everything. the trillions of bits of data that we create as we go about our daily lives are being stored, and increasingly examined. governments, companies, medical researchers, and now the police say that they, too, can exploit its potential gold mine of information. a law-enforcement intelligence people are turning to data to find patterns, clues to help solve crimes. and there are hints that some data may even help to predict crime, too. here is susan watts. >> you might think it is standard practice in crime and intelligence to look for patterns in criminal behavior, but the clearest patterns only emerge when you have masses of data and a good way to analyze

it. whether that is policing a tough neighborhood or investigating a vast terror network. >> this is where they sort out useful information from huge volumes of data, making out crimesions from where happen and people and events. disentanglingn complex networks of criminal activity. >> there are some people you can find and osama bin laden is just a way here. >> he sells software that makes sense of patterns. it is useful for modern migration, too. it can help identify culprits but in the old -- their own work force. by understanding how employees have been communicating with the outside world. >> you can see these red fans

around the edge of the diagram. those are external e-mail addresses. the internal nodes are green. are readee that there notes in the center of the network. those are particularly interesting because the external notes are frequently used by internal people. that could be for legitimate reasons, but a legitimate reasons, too. >> battlefield information collected by the soldiers and sensors in the national theater -- in the international theater is exploited. of data,are mountains literally. larger networks are hard to think about. this network is a network of terrorists. the people in the network are represented by flags, which is a country of origin. but even with that information in the network, you cannot see

the dynamics of the network, how it is held together. we are able to combine the people from a particular country into another network. that allows you to understand the interplay with the strength of connections with the -- between the individuals. >> he could not tell us exactly how the u.s. army is using his offer because it is secret, but the point is that intelligence in the field often needs real time information. they helped make sense of it. but that is all still just visualizing. what if you could do something more? the u.k. forces in have built up masses of craine data through years of -- of crime data three years of police work. now they have people to analyze it to build a picture of a possible future and predict crimes that might happen before they take place.

>> just like other police forces, it can't contributory is having to cope with -- kent constable dilatory is having to cope with police cuts. every crime is fed into a predictive system, the idea being to build up a database of information so that the police can identify hot spots and make sure officers are in the right place. the system combines historic crime figures with elements of psychology, such as the fact that burglars tend to focus on areas they know and target neighboring houses after a burglary. >> it is not simply looking back to see what would happen in the future.

is an areaok, this where there is a high risk of a crime taking place because of a number of factors and not simply what has happened before. this identifies very small areas, 500 square feet, where highest that a crime will take place. >> you can see your there are 20 boxes to to be did -- distributed at the moment. this is not about driving around the box in a car and -- but getting out of the car and being seen in the area. 15 minutes in one of these boxes >> but could big data be used to do more than calculate the risk of siegel crimes? could it be used to learn from what we know of crimes in the activity for up to two hours.

past to stimulate crimes of the future? that is what researchers in london are doing. using what we already know about the spread disease to create a --el of a spread a variety the spread of a riot. >> we have managed to simulate the london riots. thinking about the data mathematically, we can create a representation based on the individual behavior where things are likely to kick off. rare in are relatively the uk, so having a model means that police can try out different strategies. this is based on the metropolitan police's own data. >> you have created a simulated environment by drawing all the data together to then possibly be able to practice and rehearsed these things in the

future, or in a real-life scenario taking these applications forward to think about when we have a right going on, deploying resources to this particular location. what impact might we see? >> when you start to it appreciate the power of this approach, you might wonder why police are not using this kind of data and software more widely. >> the police have such a wonderful can-do attitude, but their focus is often toward tackling incidents when they happen. something they have overlooked and are not doing enough of is dealing with larger volumes of data. take the patterns and use that for day-to-day strategies. and the longer term crime- prevention initiatives as well. >> but some think there is a fine line between better

policing using data from past experience and bringing together separate data sets to draw conclusions that might be plain wrong. if they link up the number of people that they thought might be a problem with the potential to riots and they were stopping people and turning them around on the motorway because they felt they might be entering manchester to commit criminal offenses as part of the riots. your data is not linked to an individual. it is linked to a vehicle. some of these people have never been convicted of criminal offenses. and some of them may have perfectly legitimate reasons to enter manchester. >> greater manchester police told us that in unique circumstances they stopped people with previous convictions following intelligence and only as a temporary measure. they checked that they have the

right people before deciding whether to let them through or not. and they're also working with the community. it is that last point that and make pickles things should be the lesson more -- learn from the riots. >> crandon vettel please where crime is happening -- crime data tells police where crime is happening. what would happen if i during a into a computer and you suddenly realize that a gang problem is going to move three streets away? that information comes from the communities, not the technology. it is dangerous when police see technology as a quick fix. in reality, it the issue is that the police do not have relationships with the individual communities. tackleuse of big data to crime is in its infancy. before we can judge whether it has the potential to be truly revolutionary and predict crime, police and intelligence agencies

will first have to embrace the idea that data crunching can do more than simply speed things up and save money. suicide is a taboo subject in many societies across the world, which is perhaps the one reason why those who contemplate it find it so hard to seek help. in fact, worldwide, suicide is one of the leading causes of death among those between 15-44 years old. disturbingly, the rate of suicide has increased globally since 1950, and there is a clear gender divide with men far more likely to take their lives than women. the u.k. has seen a similar gender split in the rates of suicide. what is driving this male despair? tim samuels' reports. we should make clear that some viewers may find the content of

this piece of setting. -- upsetting.seen a >> it is very hard for men to simply say, i need help. >> it creeps up on you so slowly until suddenly company you are at the edge. -- until suddenly, you are at the edge. >> we talked with his best friend half an hour before he died and he gave nothing away. half,do not do this in gather to talk openly about male emotional vulnerability, the pressures we face. to shed a little light on this darkest of statistics, that men are three times more likely to take their own lives, i brought together a group with direct experience, men who have attempted suicide the families left behind, and mental health professionals.

-- upsetting. coming up to a year, almost to the week, since you attempted to take your own life. >> it is. the mind is a funny thing. can notny how you butget things, of course, you can put things to one side and when you say it like that, it does hit you. i feel that very raw. but it is amazing, also, the progress that you can make in a year. what was going wrong with me? i had set up a new company. we had gone through ideas, which is a very stressful -- we had gone through idf, which was a very stressful thing to go through. . had a court case

i was being prosecuted for assault. my marriage was not a good place. down allre to write those things on a piece of paper and, you know, even for the strongest people, actually, everything was crumbling apart. i could not cope. commit suicide. it is very hard for men to simply say, i need help. beause men are meant to tough. >> his story is incredibly common. there are thousands of men out there knowing exactly where you where youcarried --

have been. >> the last five years have seen a sharp rise in suicide amongst men in their 40's anderle 50's. -- and early 50's. >> in these times, it is about economic loss, loss of a job, loss of a career. the profile of people who commit suicide is very different than the profile of those who come and look for help. there is a population out there that psychiatrists like myself do not get to see. the first family's hear of it is when their life is lost. i think, had he spoken with friends, how different it would be. >> how long ago did he die? >> it will be six years ago this june. .t had not crossed my mind obviously, we did end up separating. i know that he did go downhill

from there and became quite depressed. but he was very up and down. had mentioned it before and i've never believed he would do that. that is something i felt guilty about for a very, very long time. i had no idea that he would do it. i was so shocked when he actually did it. people say all sorts of things when they're going through difficult times. and breakdowns of relationships. would doer thought he it. if i thought he would do it, i would have, you know, done my best. what i know now, i would have tried to help him. heard the news, what

did you think? , there all of this anger is nothing to direct at anyone. you care about them, but you are also angry that they have left the situation. i do forgive him. and i now understand why he did it. i accept the fact that he was on well. peace now.my own i understand that he was just in such despair and that was his only way. and i honestly know this, he felt that we would all be better off without him. case,sly, that is not the but that is what he truly believed. sadst feel really, really that he could not have come forward oregon and spoken to somebody.

he talked to his best friend -- come forward or gone and spoken to somebody. he talked to his best friend for half an hour before he did it and he never said anything. >> the truth is, when you're at that stage, you do not have the ability to rationalize. i have two children who were -- one was in his teens and one had just turned 20. you cannot think of them. you do not have the ability to think rationally and put things into some sort of perspective where you can say, how will they cope with it? how will they deal with what i've done? those thoughts are not there. >> in a way, that is quite comforting to hear. that is a question i've always wondered. no, was he thinking of me and the children? having dropped them off at school that morning, shirley, if he were thinking about them, you could not do it. i appreciate your saying that,

because it helps put my mind a more at peace, that he was too far gone with the depression feel the emotions. i guess, you would have to be completely detached emotionally to do that. moments, the suppose, in those part of what would have pulled you back your thoughts of your family. or was it just that physically, you could not do that? >> all you can think about it ending the english and the pain, mental pain. it is not physical pain, which would be easier to deal with. then you have something you can treat. but when you have mental anguish, it is a black cloud that completely enveloped you and you cannot see through it.

relationship of break down, aren't redundancy from work. i left the relationship moments, part of what would with pretty much nothing, became homeless. it is a horrible situation. you are in your mid 40's and suddenly, you're thinking, i've got to start again with nothing. it was just pure chance that stopped me. what happened was, the night before i add happened to look on the internet and got a number for the samaritans. iran the mobile -- the number on my mobile phone. somebody answered and i disconnected the call. i did not feel i could speak to anybody. the next day when the event was just about to happen. i got my phone out of my pocket and i started looking through the last dialed numbers on there. and i was looking and thinking, this person will probably miss me.

this person will not care. and eventually i scrolled down to the samaritans number. and to this day, i do not know what made me press the dial button, but i did. that is what stopped me from doing what i was going to do. i find it hard to look at you are a reminderou of what my family could have been going through. it is tough to see you suffering and think, i could have put my family through that. i do feel for you. >> depression is a disease of isolation. , youyou isolate disconnect. and i think that the way we are leading our lives at the moment, and in particular men, we're

disconnecting with our fellow human beings. i think that is the problem that we may be are not looking at, and we need to. >> i know from the study and from the work at the university morewe can see far suicides as a result of the economic recession, the majority of which will be men. >> does background factor into this? if you are poor, down the socio- economic scale, are you more likely to end up taking your life? >> it is true that lower socioeconomic groups are more likely to take their lives, but suicide does not have great respect for people and higher incomes. it does not work out that way. >> it might not be fashionable to say so, but you think there's any correlation between feminism and the rights of female opportunity and equality

and where man's mental health rates are now? >> equality is great. it is fantastic. but i think men have lagged behind. i think we have forgotten a lot about what men have to go through as well. >> you're not going to talk about those sorts of things which were made. you're not going to start crying in front of your mates. they don't know how to deal with that. you've got to try to go seek professional help when you do not know what is happening to you. >> what works? what has made a difference? what has you sitting here a year later feeling much better about things? >> the one key thing was group therapy. it is amazing, the bond between you. that helps enormously.

>> therapy really helped me. it made me look at what i was going through. it made me question my thought process. >> it is quite emotional sitting here with you guys, much the same as -- and i'm so glad to have many both and i'm so glad that you sought help. i just wish i could have done the same, really. >> that was tim samuels. if you have been affected by the content of that report, you can contact the u.k. support group, 448457909090on + jo@samaritansjoe
