At the Libertarian Party's request, the Township of Edgewater Park (Burlington County) repealed its "Disorderly Conduct" code. While not strictly a loitering code, the Disorderly Conduct code sought to prohibit conduct such as "us[ing] offensive words in a public place which are inherently likely to provoke an immediate violent reaction."
The original ordinance, repeal ordinance and the LP's letter to the Mayor and Council are on-line at http://ogtf.lpcnj.org/2010279Pw//EPPreempt.pdf
