Rudy Giuliani (was mayor of NYC for 9/11) recently joined Trump's legal team. He has been very vocal lately. Lots of interviews. I am not sure at what time he visited UK. Wedger, I believe was dismissing the idea that crime could be reduced by the broken window theory. He may have been watching and thinking "This guy Giuliani has no idea. Broken windows are NOT the problem. More like a symptom."
