Interesting discussion.
My comments as far as hot pursuit. As jmm has mentioned in jurisdictions within the US, states,counties,cities have special procedures that allow them to do this. In the International situation you would also need these agreements before or you could have big problems

Also inside the US, Law Enforcement is responsible for paying for everything they break or damage in the act of the pursuit. That could be a real issue with International pursuits if you injure,kill a lot of people or destroy a lot of property.


Much as been talked about the law in a COIN/GWOT type environment and this is a classic case where the Lawyers should be doing something to allow such agreements between countries and on a larger scale the US legal community should have reviewed and or made recommendations to change or modify any International legal agreement that is binding on the US to make sure the enemy can not use it against us in away that the original agreement was not intended. Synchronize the Spirit of the Law with the Letter of the Law.
