ehm...you have no rigths to go everywhere you want killing whatever you want as the US has done. USA is not the owner of the world.
There are extradition treaties (is writed like this?) and borders for something. If Colombia wanted, they should have:
1) Talk with Ecuador about this issue in order to enter ecuatorian territory to get the terrorist
2) Make a good plan and capture the bastards alive and cover it like it was near the border to avoid any territorial issue.
Instead of that they went the Bush way: Enter, kill, show it to the world without thinking on the consequences and sit back to enjoy your glorious justice (tm)
