The last season was sir yes yes and that was roughly a couple of minutes after right yes. I would offer exhibit 1046 and you. 826. And forty cent torn 264. Worms or person scissors and permission to publish. So again it's a little harder to secede in this particular photograph but if we look in this general area here. Correct you pretend you can see. The placement of in the correct. I was you don't hear that please and yes. I have here we have what appears to be an issue and coming over the top of mr. Floyd's children who have. That's good news and that would be angled in towards the Smart Car correct. Current. Take the afternoon. Syria and showing you what's been marked for identification purposes as exhibit 1047.

Yes and aren't there times where you have had to use your body weight to use to hold a suspect down for ten minutes. Somebody should. Helps me over ten minutes. I don't recollections. Is it possible. Just lost. And there are circumstances again that an officer have to take into consideration in terms. Continuing to use their body weight. Regardless of whether the person is resisting or not resist and. Let's sure. Sometimes an officer is as calm called for EMS correct. That's current and sometimes an officer may hold the person. Using their body weight to restrain them awaiting the arrival of the IMF's current. Yes you done that yourself. And sometimes you have to ensure it wasn't fair to say that you've had to train officers. To use their body weight to continue holding them. Until PMS arrives. As long as he didn't control and yes. You'd agree that. A scene where forces been used. And a crowd can congregate and is voicing their displeasure or their concern or whatever you wanna say. There can be chaotic situation for an officer. Yes. And you would agree also that what you touch screen Minneapolis police officers to do it relevant to their use of force. Is to consider the totality of the circumstances. Agreement yes. And you train officers that the decision to use force is from their perspective. Yes you not to perspective. Hindsight being torn torn. That's true that's the specific policy of Minneapolis police department. And we'll trend vs commerce. Back that is encapsulated or incorporated into the Minneapolis police department policy on the use of force current current. Because situations are rapidly evolving correct that's her and sometimes just because it. In the incident just ten minutes long or twenty minutes long. That doesn't mean that it can't instantaneously. Change. Just heard from. What may not be a threat 12 can be a threat the next. Carruthers.
