I think the last time ranchers tried defending their property, they were sued by the ILLEGALS and ended up having to give their ranch to them.
In that case, we clearly need laws that recognize and explicitly enumerate (and thus protect) the rights of ranchers to defend their own land. Ranchers and other homeowners in the most affected areas need to band together en masse and lobby for specific, written proposals in group meetings with their legislators. Numbers talk. So do letters to the editor of local papers.
