00 buck won’t carry a mile or two and kill that woman sitting at the bus stop. It wont pass through house walls and kill granny in the kitchen 200 yards away.
Sorry but 00 buck will fully penetrate house walls. May not get granny in the next house but it could easily get granny two rooms away.

It also won't penetrate most body armor - something to maybe consider, given the availability of inexpensive surplus vests & panels. The LEOs responding to that North Hollywood bank robbery a few years back had shotguns, but ended up having to borrow rifles from a local sporting goods store...
