4.01 nonviolent protest and persuasion
This Women's International League for Peace and Freedom (WILPF) banner must be the most textually dense banner I've ever seen, and certainly the most chock-full of legal history. I saw it at the US Social Forum in Detroit (USSF2010).
The No Child Left Behind Act of 2002 (NCLB) required schools to hand over identifying student information to military recruiters. Military recruiters routinely use these lists to try to meet their quota, known as their "mission," by making repeated and persistent phone calls to students and family members. And in order to meet these quotas, too many military recruiters lie to students (see a compilation of military recruiters caught lying on tape).
