Actually, the Democrat Daley mob machine IS responsible for most of the factors that contribute to the high murder rate. The first Daley (remember the 1968 Democrat National Convention there - riots, police brutality?) wanted very strict controls on guns and (his own word) "niggers." It was Mayor Richard J. Daley who picked the locations for public housing (many southside) and then isolated those neighborhoods to keep the "problems" away from "good" people.
There is little evidence Richard J. Daley was specifically biased against individual Blacks, he clearly courted their votes and established a close connection with Black Chicago community leaders, but his actions created the "welfare ghettos" of the Southside where Black on Black murders are the highest in the nation. It is worth noting that many of the Chicago Black leaders have "interesting" financial ties to the Daley mob, and several Black leaders (almost all who opposed any Daley agenda item) found themselves convicted of receiving bribes or other financial improprieties.
It was Mayor Daley who established community bosses and created the local concept of community organizers (think Obama) as political tools of the Daley mob. It was Mayor Daley who intentionally understaffed police stations in or near housing projects and refused to allow any police action to reduce crimes in the "projects." Although Richard J. is long dead, and his son Richard M. is no longer mayor, the Daley mob still runs Chicago. Rahm and Obama are both long time associates in the Daley mob. Rahm's problems are mostly because he is not as capable a criminal as the Daleys.
The clearly criminal organization that is the Chicago Democrat party machine (Daley Mob) is strongly supported by liberal democrats. The 70 year history of "social reform," liberal influence, one party politics and the clear history of vote buying, long dead voters still voting Democrat, 100% democrat votes from many polling places and registration drives (ACORN) that sign up thousands of voters in parts of Chicago where only 100s of people live, continues to dominate Chicago.
So, larryfisherman, the murders in Chicago ARE about politics, and "liberals." At least the criminal organization, the Daley mob, claiming to be liberal democrat - IS the reason Chicago sees 500 - or more - young black males murdered every year and thousands more shot, knifed or beaten.
