Its an interesting video on why you should not speak with police when questioned.Even if you are innocent or guilty. The professor advocates using the 5th amendment right.

It is some common sense information, but he validates it and demonstrates how you could implicate yourself. Even if you state the truth.


Although he does not state how you should politely tell the officer you do not wish to speak with them.

The video is limited to only 20 people watching at a time. If it doesnt load then give it a few clicks. It took me about 3 minutes before I could play it. disclaimer for the whiners though, it is 20 informative minutes of your life that you will not get back.
