I don't fear the police either, but neither am I going to stroll into a police station without a layer. While on the subject, the blame for false imprisonment does not rest solely upon some LE procuring false confessions. The blame rests also on judges, the appeals process, and other components of the justice system, including that it can take years, post conviction, for new evidence of innocence to be considered, if it's considered at all. MOO
Yes the UK that would be unheard of to walk into a police station if you was simply walking on off the street with a tip with a lawyer.
So completely different cultures.
