I'm sure they were told politely to not do something like that so they didn't.....Kind of like the IRS documents requested. I actually read in one the articles that the IRS was asked to refrain from destroying confidential documents and memos that could be used against them in a court of law. Can you imagine that? "Hey honey, I got a letter from the police today. They told me they are working on getting a search warrant for our house and to please refrain from throwing any contraband away that could be used against me until further notice. Wow, that was nice of them!" Welcome to the new normal.
