If the officer reasonably believes the warrant is valid, then the officer is protected from any legal (or civil) consequence. However, the key phrase to that is "the officer reasonably believes".
If someone manages to prove that the officer "should have known better", or that the officer lied in order to have the warrant issued, the officer can be held liable, as they knew the warrant was invalid.
All they are doing is carrying out the act of arrest, or search. When a warrant is issued signed by a judge, the officer is acting on the good faith that the warrant was properly applied for and was approved by proper judicial review. IF a defense attorney can prove that the warrant was improperly issued warrant it is not the arresting officer who is at fault since he was acting on "good faith."
Most felony arrests are decided by the arresting officer. A prosecutor will then decided whether proceed with the charges or change them accordingly.

A certifying officer's maximum level of pecuniary liability for erroneous payments is typically limited to the amount of the erroneous payment itself. This liability arises when a certifying officer certifies a payment that is later determined to be improper due to a lack of legal entitlement or other errors. However, if the officer is found to be negligent or to have acted with willful misconduct, they may face greater liability. Specific limits can vary based on agency policies and applicable laws.
