Like it or not Free Speech is in the American Constitution, but then they would replace it with the Mexican Constitution which doesn't have it. These groups want to end the ability of Americans to protect their own private property since so far that's all these so-called "vigilante" groups have been doing. We have the right to stop trespassers on our private property but private property isn't something these Marxists believe in.
We sure don't need any more people in this country that think our laws don't apply to 'them.'
