In Ratliff, the Court instructs:
To preserve error about the illegal seizure of evidence, a defendant must either file a motion to suppress and obtain a ruling on the motion or timely object when the State offers the evidence at trial. If a defendant waits until the State offers the evidence at trial, the objection to the evidence must be made before a witness gives substantial testimony about it.Ratliff involved the seizure of drugs and drug paraphernalia. The defense filed a pretrial motion to suppress, but failed to obtain a ruling prior to trial, opting to wait until the subject arose during trial to object. The problem was that the trial defense attorney allowed the police officer to testify about the search and the items he seized before making an objection to the actual admission of the exhibits. A bad strategy says the 2nd Court.
[A]ppellant's failure to object at the time [the detective] specifically described the physical evidence and explained how he found that evidence forfeited any error associated with his objection to the State's later introduction of the evidence.The Court also included a few examples of similar blunders in other cases.
In Tell v. State, an aggravated robbery case, the defendant attempted at trial to suppress the admission of a ski mask that police officers obtained from his residence without a search warrant or consent. 908 S.W.2d 535 (Tex. App.--Fort Worth 1995, no pet.). But the defendant allowed a police officer to answer four questions about seizing the ski mask before objecting to the evidence. On appeal, we concluded that [b]ecause Tell failed to object at the time the ski mask was mentioned and allowed further questions and answers before finally objecting, he waived any error in the admission of the ski mask.
Similarly, in Turner v. State, the defendant contested the trial court's admission of evidence that a detective had seized from his vehicle after his arrest. 642 S.W.2d 216 (Tex. App.--Houston [14th Dist.] 1982, no pet.). The court of appeals held that the defendant forfeited his objections at trial by allowing the detective to testify “extensively to the arrest and the items found in the search. The appellant did not object to the testimony but only to the five exhibits.Moral of the story: Objections must be urged at the earliest possible opportunity. If you try to wait to object in order to spring a tactical trap on your opponent, you may be actually springing a trap on yourself (and your client).
