My assumption is that you have not been to Los Angeles lately?
RPG's, probably not.
AK47's and other powerful weapons. Yes.
Some kids gunned down just the other week in a "gang" war.
Are all of them violent? Of course not. But with an open border, how do we know who is an who isn't?
One innocent victim is one too many. And LA alone has hundreds each year. And that is only one city.
These naive posters haven't been to northern CA, either. The Modesto Bee has been following a Mexican street gang that has been invading homes, raping the women and terrorizing the community.
They are part of a gang called the Nortenos.
Plus, 25% of our convicts in CA prisons are illegal immigrants, not to mention the cons that are here "legally."
