Law-breakers? Since when are American conservatives in favor of government mandates overriding property rights? Or, riding rough-shod over the individual landowner... people have settled because they can’t afford the fight.
Since the founding of our country. Eminent domain is in the Constitution, look it up. Now I didn't support the Kelo decision, thought it was abusive, but if it weren't for eminent domain, I wouldn't be able to drive down the Interstate because someone, somewhere would refuse to sell their property that was smack dab in the middle of the road. A border fence is absolutely necessary much as the nation's Interstate highway system is. The people that are opposing it, are doing so for economic reasons because they receive a lot of money from the other side of the border.
1. When it come down to national security vs. private property rights,
2. When our nations sovereignty is at stake.
The Constitution requires the Federal Government to protect our Country and each state from invasion. The duly elected representatives of the citizens have passed a law requiring a fence to fulfill this Constitutional mandate. This overrides individual property rights, although the property owners are to entitled to compensation.
