You & The Police
Watch both videos (part I above; they're also permanently posted on the WRSA left margin under "Practical Resources"):
Never Ever Talk To The Police - Part I
Never Ever Talk To The Police - Part II
Then pass them on, while you practice saying "I want my lawyer" - and absolutely nothing more.
The forty-five minutes spent watching these vids, along with 15 minutes of practice 3X/week, is the smartest time you'll spend this weekend.
