An Army battalion reports for morning PT and are surprised to see their Commanding Officer. They are called to attention. The CO then orders: ” If your mother is still alive, take one step forward.”
He then looks to his right singling out one Private: “ Not so fast Kowalski!”.

The Washington Post published a clear video of federal agents removing Alex Pretti's handgun moments before he was fatally shot. There's nothing in the video to suggest Pretti even reached for his weapon.

NYT video review confirms this. Pretti had a 2nd Am right to carry a firearm. But even if he didn’t he wasn’t pointing it at anyone or threatening agents. There is no legal justification for the execution-style shooting & no basis for DHS’s claim he was there to massacre them. He was a helper.
Brandishing is a legal term that means to display all or part of a firearm, or otherwise make its presence known to another person to intimidate them, regardless of whether it's directly visible to that person. Given the video, that's not what Alex Pretti was doing when he was shot & killed.
Important context, this is the victim’s behavior BEFORE being tackled
He’s not threatening, he’s not brandishing, he’s filming
He’s not threatening, he’s not brandishing, he’s filming

Alex Pretti was an American hero. He saved lives. He protected people. He cared deeply about his community, unlike the murderous thugs who killed him.
The very last thing he did was try to help a woman who had been pepper-sprayed and violently shoved to the ground by ICE. 1/
