I've been a part of a protest in the past, and yes, if the cause was right I'd do it again. I did it in high school in protest to a strip search that was done to a whole gym class without police present OR parental permission. Some of the students in the class refused to be strip searched and left the class. Some went to their next class, others just left school entirely for the day. I was one of the students who left entirely. Those of us who refused the search and/or left were suspended for 2 weeks, not allowed to attend any after-school functions and were not allowed to come back to school until both the student and the parents signed a "behavior contract". This turned into a HUGE battle between the school, school board, students, parents and Sheriff's office. Anyway, the suspended students, other students who were uninvolved, lots of parents and even people having nothing to do with the problem gathered several times across the street from the school in protest of the whole thing. Also, we were pushing for criminal charges to be filed against the school principal (who conducted the search along with 3 gym teachers and an office assistant), for the students involved to receive formal letters of apology, and for the suspended students to be reinstated as "good school citizens" (no kidding, our school used these stupid terms). It ended up that the suspended students were un-suspended and fully re-instated, the ACLU got involved and the students who were strip searched received $10,000 from the school as compensation for their traumatic experience (those of us who refused to be searched weren't included), and the principal got what amounted to a slap on the wrist because he was only 3 years away from retirement and had been the principal for this school since 1971 (this happened in 1998).
