Generally, the only people who want to watch film of people really getting their legs blown off as regularly scheduled "entertainment" are those folks who get their rocks off from watching that stuff.
What would likely happen if your proposal went through: the American public would demand that the land mines be removed.
You want to solve the problem? You're going to have to work within three constraints:
1. The Constitution. This rules out measures that require throwing out the requirement for "probable cause" before a cop demands ID. Speaking Spanish is not probable cause.
2. The budget. Beyond a certain point, Americans are not willing to pay for border security--that point being where it either raises taxes or cuts into other services that they want government to provide.
3. The moral sense of the general public. Proposals involving mining the border, turning the border into a free-fire zone, etc. are thus non-starters.
And what exactly is that "point"?
NEWS FLAH, Poob:
The Iraq War is going to wind up cost the American taxpayer a quarter of a trillion dollars.
1) Would the people have voted on such a thing?
2) Your premise is dead wrong. The government of the United States of America is obligated to secure the border from invasion. That's right -- WE'VE BEEN INVADED.
But the Bush Administration has decided NOT to treat this invasion as anymore a priority then an IRS audit.
3) Taxes will be raised, anyway. Whom do you think is going to paying off the quarter trillion dollars?
