On October 22nd there is going to be a series of marches taking place across many US cities and a few places in Canada to protest police brutality and violence against the people. I've just recently found out about this and will be going to the local march. The climate rally done in unison with NY was a blast to attend so here's to this one being also.
Anyone interested in attending check http://www.october22.org/ and http://stopmassincarceration.net/ (events) to see if there is a rally organized in your locale. It might also be posted in your local newspaper. Some of these rallies are happening mid-day and those attending will be taking half a day from work to join. If you cannot attend but would still like to contribute, you can do so by forwarding the news - informing your friends and anyone you know who is politically active, linking this event on Facebook and other message boards, posting about it in your local craigslist events section, and however else you see fit.
