How many more incidents of this variety before foreigners (and foreign investment and foreign inventors and foreign entrepreneurs) stop coming to the US? After reading this and listening to the latest episode of "This American Life" (http://www.thisamericanlife.org/radio-archives/episode/456/reap-what-you-sow?act=1 http://www.thisamericanlife.org/radio-archives/episode/456/r...), I can't help but wonder if the right in the US will "reap what they sow" and end up with an impoverished shell of an empire that no one wants to illegally enter. Edit: Based on the down votes this comment is receiving, I assume some people disagree. I'd be curious if the source of that disagreement is a feeling that this incident will not have any impact on the likelihood of other foreigners visiting?
