US Presidency
1886

When citizens of the United States voluntarily go into a foreign country, they must abide by the laws there in force, and will not be protected by their own Government from the consequences of an offense against those laws committed in such foreign country; but watchful care and interest of this Government over its citizens are not relinquished because they have gone abroad, and if charged with crime committed in the foreign land a fair and open trial, conducted with decent regard for justice and humanity, will be demanded for them. With less than that this Government will not be content when the life or liberty of its citizens is at stake. Whatever the degree to which extraterritorial criminal jurisdiction may have been formerly allowed by consent and reciprocal agreement among certain of the European States, no such doctrine or practice was ever known to the laws of this country or of that from which our institutions have mainly been derived. In the case of Mexico there are reasons especially strong for perfect harmony in the mutual exercise of jurisdiction.
