Well, look, I am not the one assessing the situation and there seems to be a lot of conflicting reports out there, many from less than reliable sources. I trust those in charge to make the assessment and as long as people aren't getting hurt, charging in there is not the way to go - in fact that pretty much guarantees people will get hurt, both the protestors and law enforcement. As long as things are calm, they should keep it that way. If they really aren't calm, then something should be done. The idea though is sound.
