You are instructed that under our law no evidence obtained by an officer or other person in violation of any provisions of the Constitution or laws of the State of Texas, or of the Constitution or laws of the United States of America, shall be admitted in evidence against the accused on the trial of any criminal case.
You are further instructed that a peace officer may arrest an offender without a warrant for any offense committed in his presence or within his view. A police officer may enter a residence without a warrant if he has probable cause to believe that an offense has been or is being committed and there are exigent circumstances which make it impractical to obtain a warrant. By the term "probable cause", as used herein, is meant where the facts and circumstances within the officer’s knowledge, and of which he has reasonably trustworthy information, are sufficient unto themselves to warrant a man of reasonable caution to believe that an offense has been or is being committed. Exigent circumstances may include preventing the destruction of evidence or contraband.
Now, bearing in mind these instructions, if you find from the evidence, or if you have a reasonable doubt thereof, that on the occasion in question, (NAME OF OFFICER) entered a residence without a warrant and lacked probable cause to believe that an offense had been or was being committed, or if you find from the evidence, or if you have a reasonable doubt thereof, that there were not exigent circumstances which made it impractical to obtain a warrant for an entry, if any, then any evidence obtained within the residence would be illegally obtained and you will wholly disregard the testimony of (NAME OF OFFICER) as it relates to the events following entry into the residence, if any, and disregard evidence found in the residence, if any, and not consider such evidence for any purpose whatsoever.
