I disagree. When political protesters are using violence, and violating the law in a scale larger than domestic law enforcement can handle, it needs to be stopped PERIOD. The Constitution does NOT allow violent punks to protest violence using the very tool they are protesting. It allows for PEACEEFUL assembly, and redress of grievances. Ulitmately, they were WRONG. The damage done to this Nation by Vietnam antiwar protesters has been immeasurable. We have been a divided nation since then, with no national will, and absolutely no concept of percervering to victory. Anyone who thinks when the going gets tough it's okay to quit is nothing but a loser, IMO.
