David Blaska mentions that Madison’s Mayor is holding a meeting this morning. The meeting includes Madison School District Superintendent Dan Nerad:

Several landlords have invited the mayor to take up residence on our troubled streets so that he can experience firsthand what many of our neighbors must put up with in their daily lives. Some of them extended the invitation/challenge even before — hours before — the murder. [Let the Mayor come to Meadowood.]
In the meantime, Mayor Dave Cieslewicz has made good on his promise to convene a meeting to deal with the “Lord of the Flies” chaos in certain sections of southwest Madison.
The mayor’s meeting will be held Wednesday morning — exactly one week after Madison woke up to the news that a 17-year-old boy had been shot to death at Leland and Balsam Roads the previous evening, June 9, on the troubled southwest side. Shortly afterward, three 16-year-olds boys were apprehended and charged in connection with his murder — two of them as adults for first degree intentional homicide.
Some of us, including Ald. Pham-Remmele, saw the trouble coming long agI blogged on May 20, quoting a neighbor, “Unless the police are able to get a handle on the roaming gangs, this summer is going to be bloody.” [Going to be a long, hot summer]

A previous post mentioned this:

Police officer Amos said the principal of Toki Middle School will not permit him to arrest children in the school, even though some of them are chronic drug users.
“These people know how to work the system,” said another. Yes, they know their rights but not their responsibilities.

Nearly four years ago, Rafael Gomez organized a Gangs & School Violence forum. The conversation, which included local high school principals, police personnel and Luis Yudice, among others, is worth revisiting.
