The cops screw up with information and do so time and time again, often by design (such as withholding info until they deem the most suitable time, releasing intentionally misleading info to protect investigation) and sometimes by incompetence. Remember Adam Lamza's 2nd AR15 police say they removed from the trunk of his car, yet on video we could all see that it was a pump shotgun. The POLICE called it an AR15. Folks went crazy for the "media" reporting the gun incorrectly, even though they were reporting what the police told them.
Here are the smart and knowledgeable police identifying clearly labeled GLOCK pistols as ghost guns. They were caught in the error and deleted the tweet.

With that said, just look at all the misinformation that came form the police during Uvalde and for weeks thereafter.
