 We've been planning it for the past one, one and a half years and it was quite challenging for us as well. We've been calling it the digital security challenge and a lot of times we were laughing that the challenge is on us to make it work because of course coming up with a scenario that is up to date in lines with what happens in the world it's one challenge but then the second one is actually putting all the pieces of evidence together in the right time and then once you have all this you cannot go back and modify and look at the scenario and say we should add some more pieces of evidence but you know as everything is digital you can see traces when you put back some other pieces so it was very very challenging. From our perspective it's been a total success because we had quite a large crowd 65 plus participants from 33 countries so discussing with the participants I think everybody find it a very very interesting and exciting exercise especially the fact that they had to team up with fellow investigators from different countries so they got to experience each other's skills and levels of expertise.
