Since President Obama was inaugurated, there have been over two thousand six hundred arrests of activists protesting in the US. Research shows over 670 people have been arrested in protests inside the US already in 2011, over 1290 were arrested in 2010, and 665 arrested in 2009. These figures are certainly underestimate the number actually arrested as arrests in US protests are rarely covered by the mainstream media outlets which focus so intently on arrests of protestors in other countries.
Arrests at protest have been increasing each year since 2009. Those arrested include people protesting US wars in Afghanistan and Iraq, Guantanamo, strip mining, home foreclosures, nuclear weapons, immigration policies, police brutality, mistreatment of hotel workers, budget cutbacks, Blackwater, the mistreatment of Bradley Manning, and right wing efforts to cut back collective bargaining.
These arrests illustrate that resistance to the injustices in and committed by the US is alive and well. Certainly there could and should be more, but it is important to recognize that people are fighting back against injustice.
