Unless I'm mistaken, by the time that the police officer would lie about consent, he'd already know if there was a video, right? The joys of discovery should reveal that.
I'd never tell the prosecution about it - that rebuttal testimony.
Me: Officer, you testified my client consented to the search of his aircraft
Cop: Yes, that is correct.
Me: There is no chance you could be mistaken [sound of the trap opening]
Cop: None. [knowing that they searched his phone completely]
Me: 100% certainty that your search was the result of consent by the defendant.
Cop: Yes.
Me: What did you and what did he say?
Cop: I asked him if he minded if I took a look in his aircraft. He said, 'No problem, or words to that effect." [boy that cheese looks good]
Me: Your honor, I'd like marked and introduce an iPad mini bearing serial number - blah blah blah
Prosecutor: Objection. This is not on the dcoument list - blah blah blah
Me: This is my client's iPad mini which was mounted on the yoke inside his aircraft, I can bring him up for the limited purpose of identifying it and certifying what I am about to play has not been altered or removed from this iPad since it was created [bring my client to the stand, its his ipad, he turned on the audio recording function when the officer arrived at the aircraft before he got out, has not changed it since, etc etc etc
Judge: Ok - solely for the purpose of rebuttal counsel I'll mark as Defendant's Exhibit 1. OVer hte object of Prosecution, so noted.
Me: Officer, before I play this would you like to alter any of your prior testimony under oath. [whats that spring noise, ouch]
Cop: Uh. [right here - the smart ones say NO - because they don't want to be cross examined under oath about their lie. The stupid ones change their testimony on the stand - the BRILLIANT ones claim the fifth amendment]
Recording:
Hello, Sir, I'm Officer friendly, I'd like to ask you a few questions.
Pilot: I understand your authority officer, but I wish to remain silent.
Cop: "Well, not sure what you have hide here,m I just ask want to ask a few questions.
Pilot: As I said officer, I intend to remain silent.
Cop: Then I'm gonna need to search your airplane here. This silent stuff is pretty suspicious. In my experience people who don't speak have something to hide.
Pilot: I do not consent to a search of my aircraft or my person. Do you have a warrant?
Cop: Sir, please. You need get down off that wing and stand over there. If you interfere with me I am going to have you arrested for interference and obstruction. I'll give you one last chance to make it easy on yourself and let me search this airplane the easy way. . . .
They will not lie overtly. They may try to claim implied consent. It is the only place most LEO's will not lie. . . at least directly or if they think they might be proven to be lying. . . they will generally stretch the truth at a traffic stop because they are dealing with the public and not lawyers - they make great witnesses - because they are such good liars.
