Liz Wheeler provides the very best frame by frame closeup analysis that I have seen. I encourage you to watch it starting at about 18 minutes. I don't think it was murder. It looks like Pretti:I watched a clear video and u can see the agent remove his gun from his back waistband before they shot him!
1. carried a gun and two magazines illegally to a protest.
2. Was illegally trying to obstruct ICE.
3. Put his hands on an ICE officer
4. Engaged in a physical struggle with ICE officers
5. Was disarmed during the fight with ICE officers
6. Reached to his back waist band
7.Came out with an object in his hand (a magzine?)
The videos also seem to show
1. A ICE agent removing Pretti's SIG P320 (A gun design know to accidentally discharge)
2. Pretti's gun seems to discharge simultaneously when the first gunshot is heard and a recoil is seen on the gun and agents arm. (I previously did not believe rumors that his gun discharged)
3. Then after Pretti reaches for his holster comes out with a dark object and after a gun discharged ICE shoots Pertti.
We don't know if the shooter agent knew if Pertii was disarmed or not and we don't know if he thought Pretii pulled out a second gun or a knife. We don't know if the agent saw Pretii pull something from his holster then heard a discharge and thought Pertii was shooting a gun.
Watch the video and make up your own mind.
BTW : SIG P320 have a history of accidental discharge. Some law enforcement agencies ban their officers from carrying them.)

Fake ignore is the best! Go smoke more meth, Ms. Fat Lame. Maybe the quality of your posts will improve.
