Personally I dont think the bad behavior of a few in the protest should diminish the rest of the group. Just because a couple of idiots threw water bottles at people doesn't mean they define the entire protest

.
To me its about equal justice under the law and the illegal immigration thing flies right in the face of justice being blind. We are selectively choosing to ignore a law because we are an empethetic nation, and I find that wrong.
I dont blame illegal immigrants for violating our immigration laws. Like I said If I felt like I had to break the immigration laws of canada or mexico to feed my family you would see me at the borders trying to get in. I feel bad for the poor souls who have to try and come here illegally just to feed their families.
However, I can not suppor their violation of our immigration laws and can not condone rewarding them breaking the law with amnesty/citizenship. Justice needs to be equal and blind, if we dont like the laws we can try to change them but we cant just ignore them.
