The 31 protesters arrested in the Penn State admin building sit-in earlier this month will be charged with “defiant criminal trespass,” police announced Friday. The charge is a third-degree misdemeanor, and carries a maximum penalty of one year in prison and a $2,500 fine.

Penn State United Students Against Sweatshops plans a rally for the arrested students at 2 pm this Thursday, May 1.

An online petition in support of the students and contact information for the president of PSU can be found here.
