Hollow points are more destructive and dangerous to the person who was shot. They cause so much internal damage that the person will not survive a wound that may have been survivable otherwise. They are banned by the Geneva convention.

I'd like a source on that final sentence if you have it.

I get the arguments for and against them, but I generally favor leaving those decisions up to the people involved.

Why don’t you Google it? Easy to find.

>It is a common misapprehension that hollow-point ammunition is prohibited by the Geneva Conventions, as the prohibition significantly predates those conventions.

There ya go. Easy to find.

Why do police use them then?

Because they are less likely to also shoot the person behind the person you shot.
