The people who were doing the protesting need to submit their names and numbers before being allowed to leave the area - - - so that when these illegal aliens are allowed into our country (to submit democrat votes, let's be honest) the US GUBMINT OFFICES IN CHARGE can direct them to the houses of the people or their parents, so they have somewhere to go when they "settle" here in America and live off the welfare system, which is their primary goal in life.  These immigrants could care less about America - - but they do want the freebies.  These "students" are enablers, nothing more.  Few people are going to see them as "warm hearted souls".  They are idiots en masse.
