Some ask you to self incriminate because they have no other way of finding out; the law only requires certain things to be disclosed and for a certain period of time.

I AM ATTEMPTING TO HELP YOU BY NOT GIVING YOU THE ANSWER AND BY TELLING YOU TO LOOK IT UP SO YOU WILL LEARN IT AND REMEMBER IT WELL.
I hope you understand and respect what I am doing for you by this. Look it up.
