Why can an officer still charge for drugs or guns found during an arrest that later gets thrown out?

While the items are often inadmissible in court if obtained improperly, the fact that a warrant was signed by a judge indicates that the officer followed the legal procedures required to obtain permission to search and seize items. This judicial oversight lends legitimacy to the action the officer took, even if subsequent legal proceedings result in the evidence being thrown out.

In many scenarios, an officer can still charge an individual based on the circumstances and other evidence available at the time of arrest, despite the inadmissibility of some evidence. The endorsement from a judge means that there was a legal justification for the search, which can still support the officer's decision to proceed with charges. The presence of the warrant often implies that the legal basis for the actions taken by the officer was sound, contributing to the overall integrity of the law enforcement process.
