@freemo @thatguyoverthere @admitsWrongIfProven Criminals get the ledgers and target the owners. It's a real thing in Australia. The gun regisration data base is busted too. That has been linked to robberies where owners and dealers have been targeted.
A popular right wing news paper published a map showing regions of highest concentration of legal guns per person which were farm communities. Those communities were targeted by thieves and still are.
This may or may not happen in your country.
