There was an incident that made the news a few years back. Lady got into an accident...EMT found the lady had a ccw and turned the pistol over to an officer. After the lady got out of the hospital the police stated they didn?t have the ability to run the background check to return the firearm. She had to get a lawyer and threaten legal action. The police then agreed to meet her at an ffl to get the background check done.
Technically the police were in violation of the law as they hadn?t had a background check done to take possession to begin with.
