Defense Questions Lt. Johnny Mercil on Neck Restraints in Derek Chauvin Trial Testimony Transcript

Eric Nelson: (00:00)
You were asked a series of questions about whether this appears to be a trained Minneapolis neck restraint.

Johnny Mercil : (00:11)
Yes, I was asked that.

And you said no, correct?

Correct.

But you hedged a little bit and said it may be some other training.

Perhaps.

What would that training be?

Using body weight to control. However, I will add that we tell officers to stay away from the neck when possible and if you’re going to use body weight to pin, to put it on your shoulder and be mindful of position.

All right. And if we can take this down and just to the witness, I’d like to display a couple of… This is page 41 of Exhibit 126. Just show this to the witness. Can you see that, sir?

Not yet.

Speaker 3: (01:10)
It’s supposed to be up.

Sorry. This is already in evidence, but in this bottom corner here, do you see a photograph of an individual demonstrating how to handcuff a person?

Yes, sir.

And that knee is across the neck of that individual, correct?

The knee is on his far shoulder.

Across the neck, the base of the neck.

The shin would be from his toes up to the knee. Yes, his shin is across the back of the neck.

All right. So that’s when we’re talking about prone handcuffing. This is a specific kind of photograph that demonstrates the placement of a knee as it applies to prone handcuffing, correct?

Correct.

And ultimately, if that person were to be handcuffed and circumstances dictated the officer would be permitted to continue to hold his knee in that same position. Agreed?

I would say yes. However, we’ve cautioned officers that be mindful of the neck area and to look for the shoulder for placement.

Okay. Perfect. We can take this down. Can we take that down, Your Honor?

I’m going to show you what has been introduced as Exhibit 56 already. Can you see that, sir?

A little glare, but yes sir.

It appears to be the-

Judge: (02:51)
You can stand up.

Sure. Yes, sir.

What appears to be the paramedic checking the carotid pulse of Mr. Floyd?

Yes, sir.

In your experience, this is already admitted as Exhibit 56. In your experience, would you be able to touch the carotid artery if the knee was placed on the carotid artery?

No, sir.

Sir, I’m showing you what’s been marked for identification purposes as Exhibit 1045, 1-0-4-5. Can you just generally take a look at that?

Yes, sir.

Now, in terms of, do you recognize that this appears to be a still photograph taken from the body-worn camera of one of the involved officers?

That’s what it appears to be, yes.

There’s a timestamp on it that indicates May 25th, 2020 at 2020 3:32.

Yes, sir.

And can you see two officers in this area here holding Mr. Floyd?

Yes, sir.

Let me clear this. Here, does that appear to be the placement of one officer’s knee and leg?

Yes, sir.

Does that appear to be across the shoulder blade to the base of the neck?

Now, the shin appears to be across the shoulder blade. I don’t know if I can tell you where the knee is.

I would offer a 1045.

Judge: (05:00)
All right. At 1045 is received.

Permission to publish. Can we clear that? Okay. So what we’re seeing here again, this is at 8:23 and 32 seconds, correct?

Yes, sir.

And obviously this is taken from one of the body cameras and here you can see down in that area, the leg placement of the officer, correct?

Yes, sir.

And based on your observation of this photograph, it appears that the shin is coming from the top of the shoulder across the shoulder blade, correct?

Yes, sir.

And it appears to be at an angle pointed in towards the squad car, correct?

Yes, sir.

All right. We can take this down, Your Honor. I think I accidentally closed. Hang on one second.

Speaker 5: (06:27)
It looks like the defense attorney, Eric Nelson’s having some technical difficulties pulling up one of the-

Sir, I’m showing you what’s been marked for identification purposes as 1046. Does that appear to be a similar angle?

Yes, sir.

And I apologize, it was actually Officer Wayne’s body worn camera, 1045 and 1046. Again, can you see what appears to be the placement of the leg of one of the officers at the shoulder blade of Mr. Floyd?

It appears so.

You can see in this area here what appears to be the back or the calf area coming across the shoulder blade, correct?

Yes, sir.

Again, the timestamp is 10:26 and 40 seconds.

Yes, sir.

And does that knee placement appear to be similar to the placement in the previous exhibit?

The last exhibit, sir?

Yes.

Yes.

And that was roughly a couple of minutes after, right?

Yes, sir.

Okay. I would offer exhibit 1046. 8:26 and 40 seconds. 20:26, 40. Okay.

Judge: (08:00)
1046 is received.

Permission to publish? So again, it’s a little hard to see in this particular photograph, but if we look in this general area here, correct, you can see the placement of the knee. Correct?

I can see the general area of the placement of the knee. Yes.

And again, here we have what appears to be the shin coming over the top of Mr. Floyd’s shoulder blade.

That’s what it appears, sir.

And that would be angled in towards the squad car, correct?

Correct.

Take that down, your Honor. Sir, I’m showing you what’s been marked for identification purposes as exhibit 1047. Does that also appear be a still frame image taken from a body-worn camera of a Minneapolis police officer?

Yes, sir.

Timestamp being 8:27 and 49 seconds.

Yes, sir.

2027-49, correct?

Correct.

And it appears that the officer wearing this body-worn camera has now stood up, correct?

It’s a different angle, so yes.

From higher to lower, correct?

Lower to higher, sir.

All right. It appears that the camera is at a higher angle looking down.

Yes, sir.

And can you see in this photograph, what appears to be the knee and shin placement of the officer?

Yes, sir.

And would you agree that it appears that the knee is placed in the center between Mr. Floyd’s shoulder blades?

It appears to be between his shoulder blades, sir. Yes.

I’d offer 1047.

Judge: (09:52)
Any objection? 1047 is received.

Permission to publish? So again, here in this particular photograph, you can see the placement of Mr. Chauvin’s knee in between the shoulder blades of Mr. Floyd, correct?

Yes, sir.

All right. And it happens to be right here that moment when the carotid artery is being palpated by the EMT.

Yes, sir.

We can take this down. Should be one last photograph, sir. Again, does this appear to be a photograph taken from, or a still frame image of a Minneapolis police body camera?

Yes, sir.

Time being 10:28 and 29 seconds.

Yes, sir.

Excuse me. 2028-29.

2028-29, sir. Yes.

Which would be 8:28, 29.

Correct.

And again, can you see the placement of Officer Chauvin’s knee?

Yes, sir.

Can you see Mr. Floyd’s head?

Yes, sir.

I’d offer 10-48.

Judge: (11:12)
Any objection? 1048 is received.

Permission to publish. Again, it’s a little hard to see here. Can you see Mr. Floyd’s head in that area?

Yes, sir.

And Mr. Chauvin, Officer Chauvin’s knee between the shoulder blades of Mr. Floyd?

Yes, sir.

Does this appear to be a neck restraint?

No, sir.

Does this appear to be a prone hold that an officer may apply with his knee?

Yes.

You can take that down your Honor. Now, you have talked about taking a or holding a person in the prone position after they have stopped resisting. Do you recall talking about that?

Yes, sir.

And are there circumstances in your career where you have had to use your body weight to hold a suspect down for longer periods of time than say two or three seconds?

Yes, sir.

And are there times where you have had to use your body weight to hold a suspect down for 10 minutes?

I’m not sure if I’ve ever had held somebody down for 10 minutes or not. I don’t have any recollection of that sir.

Is it possible?

Yes, it’s possible.

And there are circumstances again that an officer has to take into consideration in terms of continuing to use their body weight regardless of whether the person is resisting or not resisting right?

Can you rephrase that?

Sure. Sometimes an officer has called for EMS, correct?

That’s correct.

And sometimes an officer may hold a person using their body weight to restrain them awaiting the arrival of EMS, correct?

Yes, sir.

You’ve done that yourself?

I have.

And sometimes you had to… Or was it fair to say that you’ve had to train officers to use their body weight to continue holding them until EMS arrives?

As long as needed to control them. Yes.

You would agree that a scene where force has been used and a crowd congregates and is voicing their displeasure or their concern or whatever you want to say, that can be a chaotic situation for an officer, right?

Yes, sir.

And you would agree also that what you train Minneapolis police officers to do relevant to their use of force is to consider the totality of the circumstances, agreed?

Yes, sir.

And you train officers that the decision to use force is from their perspective.

Yes, sir.

Not the perspective, hindsight being 2020.

That’s correct.

That’s the specific policy of Minneapolis police department.

I believe that’s Graham v. Connor, sir.

That is encapsulated or incorporated into the Minneapolis police policy on the use of force, correct?

Correct.

Because situations are rapidly evolving, correct?

That’s correct.

And sometimes just because of an incident is 10 minutes long or 20 minutes long, that doesn’t mean that it can’t instantaneously change.

That’s correct.

Right? What may not be a threat one second can be a threat the next.

Correct.
