Hi Breza
I think there is a fine balance between adequate information and giving you all the answers. As an investigator you will often have to depend on your cunning, your ingenuity, your persistence. Thinking on your feet, they call it. When people think there's no solutions, the smart investigator finds them.
I have not read all of the certificate units in the ASSI course, but I reckon you can find many answers on the internet. I also think that ASSI wants you to have a go even if it's not spelled out for you, just to see if you use your noggin!
