Chicago clears only 25% of there murders.
A much better clearance rate than the last period of gang warfare in the 20s. Prohibition promotes criminal behavior and gangs. It is a simple concept. Address the drug war with sound policy alternatives and you take the profit out drugs. When the bootleggers lost their source of income, the violence connected to gang wars was not eliminated, but greatly reduced.
Chicago is the safest large city I have ever been in, and I have walked the near West side gang infested areas. I look like a policeman, and I have never been bothered, much like a family living in Chicago during the roaring twenties.....the civilians were mostly safe.....but if you are standing near a gangbanger, or you are in your home as a gangbanger goes by your home.......as one SA once told me....the safest person in a gang gunfight are the people being aimed at......everybody else.....God help them.
