"And Bingo was his name-O!"
Rudy Guilani did find out that enforcement of all the laws (broken windows) made a huge difference in the culture of crime in NYC.
I'm no fan of "Juliano" (as "Reverend" Jackson has called him). I'm pro-life, pro-traditional family, pro-RKBA, and opposed to B-I-G government. But I can hardly fault him in this regard. The "broken windows theory" has been proven correct so many times that anyone who denies it needs to seek immediate help.
The application to the context under discussion is obvious.
