Hi Edmund, great to know you've set yourself a goal! Although the world certainly needs crime scene investigators it is not likely that Khan Academy will go into this topic. This is mostly because KA tries to cover what will give the biggest impact (courses taken by a lot of students), but also because some of the images and text which would be relevant to that sort of education would be highly disturbing to a lot of people. 

Still, KA does have lots of background material in Science that won't be wasted if you keep following that path!

I think that would be a great idea

hey I am looking at chemical evidence for an assessment and i cannot find how it collected or stored could someone help me out 

Hello my name is Cheyenne. I would like to see KA do a forensic science program. I know tons of teens that want to learn more about it and the field is growing. i think it would be a travesty if you guys did not make a program for that. There is a clear expressed interested in the topic by many students so why not.
