Acquaitences are not even in the friends category.
So they are probably stretching the truth here. Trying to cover his ass.
Anti-gunners make much about how many shooting deaths are between "acquaintances". An acquaintances is anybody who is not a stranger. If Jamal recognizes Shlameal as a member of a rival gang, and kills him, then that counts as an acquaintance killing. If two robbers get into a shootout over how to divide the loot, and one dies, then that was an acquaintance killing.
