Making a crime a hate crime makes it easier to get the death penalty applied in states that have it. Down right backward of GA not to have hate crimes on their books.
It depends on who you talk to. A lot of these "special" laws are incredibly popular with politicians and activists, but not so much with prosecutors and judges.
The problem with hate crimes specifically is they are a "specific intent" crime. To get a conviction, you have to
prove what was on the mind of the defendant at the time of the crime.
Murder is also a "specific intent" crime, but it's fairly easy to show that a defendant
meant to pull a trigger. If you walk into a store with a gun and yell, "Give me your money!" it's not a big reach to prove specific intent that you intend to rob them.
But unless there is clear evidence that this particular crime was racially-motivated, it would be very hard to prove a hate crime. The fact that the defendants are white and the victim was black doesn't prove anything in a court of law. It ain't that simple.
And THAT messes up the much more important parts of the case.
There is a huge body of law and legal precedent that tells lawyers on both sides, and judges, what aggravated assault and murder are. There are centuries of cases, and that makes proving the necessary parts of the crime (the corpus delicti) less difficult.
Additional unnecessary charges just muddy the waters, and make it easier for a good defense lawyer to create "reasonable doubt" or for a jury to make an incomprehensible leap in logic to avoid the harder choices.
