 *Oppose - Border checkpoints are very unique from internal security checkpoints as the former separates completely different jurisdiction.  Sometimes these jurisdictions are even at war or combative conflict with one another (Russian and Georgia, North Korea and South Korea for examples) while the latter can not only be within jurisdictions, but within local municipalities.  Even Washington D.C.'s Trinidad neighborhood has security checkpoints that have absolutely no separation of government, laws, language, ethnicity or military forces.  While a border checkpoint can include an in depth screening of documents and inspection of goods which might determine the overall legitimacy of the right of passage from one nation to another, a security checkpoint can just simply be to check for specific items like weapons within a single neighborhood.
