The “Hague Convention of 1899″ (bad link btw) restricted national armies in-the-field against each other to the use of “ball ammunition” (FMJ).
It does not apply to internal, security (police) forces; which is why, every police department in the United States specifies that its officers carry hollow-point (JHP) ammo to minimize “collateral damage”.
FMJ ammo tends to give a “through-and-through” wound unless it strikes a bone, and then goes down-the-street to strike someone else.
That works well in warfare where you want to inflict as many non-lethal casualties as possible, thereby tying-up your opponents support forces in caring for the wounded; but doesn’t work well in civilian settings where you end up hurting a bunch of “innocent bystanders”, generating law-suits against the police and city for excessive use-of-force.
