In TULSA, a cop killed his (ex?)wife with a crossbow. Very quiet. The only noise was her screaming when she saw a short feathered shaft sticking out of her chest.
No registration needed.
As for title three weapons, remember at the funeral of a cop when his supervisor said he was tired of going to cop’s funerals who were killed with Uzis!
A quick check showed NO cops killed with full auto Uzis in the USA.
