I shop at the Franklin Av. Aldi's which earned the nickname "Ali's" because of the many Somali's that shop there. Personally they have never given me any problem. Most seem good people but they have the "jihadist" minority.

The big Cedar Riverside high-rise complex is majority Somali. It was recently given a "historic" designation and is being refurbished (look for the freshly painted color panels).
It is located next to a light rail station for the current Hiawatha and future Central Corridor light rails.

The situation reminds me of 1970's Quebec Separatist movement. In Montreal there were bombings and kidnapping of business executives. Corporations moved out there headquarters and factories en-mass.

I learned about this from (of all places) the commentary on the DVD for the movie "Death Race". It was filmed in a closed mile long locomotive factory. The director commented that there were a lot of empty building there because of business exodus.
