"Now, in a breathtaking display of chutzpah, the Canadian ambassador to the U.S. is warning President Obama if he does not approve the controversial Keystone XL pipeline, then he can expect similar oil trains and even trucks to enter the U.S."
I've always felt the US has been extremely lucky insofar that there hasn't been a major incident where an unarmored oil/gasoline truck has exploded on a 12+ lane major highway just by sheer coincidence on an unfortunate ricochet by the daily road rage firearm occurances.
They make armor piercing rounds down there afterall, and there is no way to control the one in a million psychos out there that do evil things like disable brakes on trains or shoot at people on the road.
I'm not sure the public truely understands the alternative to pipelines.
