Indeed, we should not underestimate the effect of police/agencies behaviour on regular citizen. It is something that shocked me when talking to friends freshly immigrated from countries like South America to London. They have a general mistrust of cops, the more cop they see the less safe they feel. On the other hand, my wife and I, coming from other European countries are very happy to see cops around. That said, since Tony Blair's "we can hold you in custody for a month without rights", or the we just shoot random people in the back after 7/7 bombing, our attitude is slowly changing. I'm not sure I would volunteer information to the police related to any hot topic without studying the risks first.
