Police took my gun for safekeeping and won't give it back without a court order. This was 6 years ago. What am I to do?

talk to a judge

its long been crushed ...

You lose: like most confiscated or recovered goods, some goes to police auctions to buy them more toys and donuts.......and most goes to their homes. Pigs.

The weapon 🔫 is likely to be in the past by now however you could seek advice from a lawyer if you had a legitimate reason to have a firearm in the first place. However if you didn't have a licence for the firearm I don't think you'll stand much of a chance

You START by telling an attorney WHY they took the gun 'for safekeeping'.
