What is it our soldiers fight to protect?  What makes or used to make the U.S. a great country?  The ability for citizens to express peacefully their ideas and views without fear of retaliation or imprisonment.

At the monument to Thomas Jefferson, who said: 

"I would rather be exposed to the inconveniences attending too much liberty than to those attending too small a degree of it."

Police brutalize peaceful citizens whose only ‘offense’ is quietly dancing in front of the monument.  The police refuse to tell the citizens they are harassing what law they are accused of violating.  They then proceed to treat the citizens with unwarranted brutality.
