Re: Nothing to hide..
The problem is that you get the phenonomon of "consolation convictions" where, once you have been shown to be not guilty of a crime, the authorities have a database big enough that they can find some kind of technicality or other to prosecute you over in order to save face. Five years ago you tweeted something while drunk that you instantly deleted but they can exaggerate how bad it was enough to drag you through the court and ruin your reputation, with your eventual acquittal doing nothing to undo the damage.
