Ease up on that: "I'd be stocking up on ammo while waiting for improvements" bit, Blue,...and especially if merely some typically White Arizona Rancher at daily mercy of heavily armed Criminally Illegal Alien Dopers, Smugglers or Terrorist Trespassing Invaders.
With Top Obama Law Enforcer Eric Holder actually one calling the shots on U.S./Mexico border, there's infinitely more a chance that some beleagured White Rancher might be brought up on gun charges,...THAN any heavily armed Criminally Illegal Alien Dopers, Smugglers or Terrorist Trespassing Invaders caught EVER WILL.
In general and since once whites were all slave owners, nasty white or light transgressors MUST be prosecuted mercilessly. Whereas once all blacks or darks were slaves, Attorney General Holder will most likely let any black or dark thugs skate.
Some call that Marxist: "Playing the race card" or just; "Getting even" at highest of levels.
