Question: Who is "Kansas Mutual Aid", "Solidarity Center", and/or "ARISE"?

I'm from Connecticut and we just had a local young man charged with setting fire to a Bronx army recruiting office. Anywho-all the solidarity emails going around direct people to "Kansas Mutual Aid." And the only action is to send them money. Who are they? I can find no information on them. And the only references are the same: the address where to send money.

KS mutual aid, solidarity center and ARISE

The Kansas Mutual Aid Legal Collective does legal defense work for anarchists and other activists. They can be reached at 913-775-1399 or kansasmutualaid@hotmail.com. The Solidarity Center is connected to the AFL-CIO. There are several "ARISE"'s. There's Arise for social justice, a low-income rights, anti-oppression membership organization in western Massachusetts started in 1985 by 4 women. There's also Arise Bookstore in Minneapolis, MN.
