We give you a free computer & you build a custom agentic system to aid in attack/defense. We'll also attack a multitenant agentic AI app hosted on #k8s. It'll be fun, useful, & eye-opening!

Quotes about Jay Beale's Agentic AI-Aided Kubernetes Attack and Defense class from previous students.

"I took this at BlackHat last year from @jaybeale and it was fantastic. Can't recommend it enough." - by Jake Williams

"I've said this before and I'll say it again,[@jaybeale](https://x.com/jaybeale)'s kubernetes training is probably the best way to learn kubernetes security right now. I took it about a year ago and learned a ton even though I've been leading Kubernetes offensive security efforts for ~2 years." - Graham Helton

"FWIW Really enjoying opening day of the class diving into containers from first principles before going into attack and defense. Honestly BEST deep introduction to container fundamentals I’ve encountered, and I’ve heard many (and teach it myself at work.)" - Kerry Bonin

"This was an awesome class! I hit the "brain full" state early on the third day. Being able to talk with the instructor and other students helped greatly. ..." - PacketGeek

You have to read this. Firsthand affidavit from one of the women who was there and recording the video. She talks about how Alex Pretti was directing traffic when she arrived. She watched him be killed in front of her. She's afraid to go home, worried she'll be arrested.
1. I am a resident of the Whittier neighborhood of Minneapolis, Minnesota. I am over 18 years of age. I am a children's entertainer who specializes in face painting.
2. On Saturday, January 24, 2026, at about 8:50 am, I was getting ready to go to work when I heard whistles outside. I knew the whistles meant that ICE agents were in the area, so I decided to check it out on my way to work. I've been involved in observing in my community because it is so important to document what ICE is doing to my neighbors. Connecting to your local community and knowing who your neighbors are is something I profoundly value.
3. I drove to Nicollet Ave. and 26th where I could hear the whistles coming from. I turned south onto Nicollet. There were already several ICE agents there and they'd set up a sort of vehicle convoy on Nicollet and 28th. There were also about 15 observers there, recording and observing ICE.
4. I saw ICE agents surrounding cars and punching car windows. I also saw them stopping vehicles further down Nicollet, so I backed up because I didn't feel safe continuing on.
5. I noticed a man sort of acting to help traffic move more smoothly. He helped me find a place to park. I got out with my whistle and my camera. I went over to him and said something like, "I'm going to film and use my whistle."
6. It seemed like most ICE activity was happening a little farther down the street from us, near 27th. Someone was being thrown to the ground.7. I started recording. There was an agent by a car across the street. Two observers were a few feet away from the agent, blowing their whistles. One was wearing a backpack.
8. I and the man who was observing and helping direct traffic were standing in the street. There was a phone in the man's hand recording a video.
9. An agent approached and asked us to back up, so I moved slowly back onto the sidewalk.
10. The man stayed in the street, filming as the other observers I mentioned earlier were being forced backward by another ICE agent threatening them with pepper spray. The man went closer to support them as they got threatened, just with his camera out. I didn't see him reach for or hold a gun.
11. Then the ICE agent shoved one of the other observers to the ground. Then he started pepper spraying all three of them directly in the face and all over. The man with the phone put his hands above his head and the agent sprayed him again and pushed him.
12. Then the man tried to help up the woman the ICE agent had shoved to the ground. The ICE agents just kept spraying. More agents came over and grabbed the man who was still trying to help the woman get up. All three of the observers looked to have been badly affected by the pepper spray. I could feel the pepper spray in my eyes.13. The agents pulled the man on the ground. I didn't see him touch any of them-he wasn't even turned toward them. It didn't look like he was trying to resist, just trying to help the woman up. I didn't see him with a gun. They threw him to the ground. Four or five agents had him on the ground and they just started shooting him. They shot him so many times.
14.1 don't know why they shot him. He was only helping. I was five feet from him and they just shot him.
15. The video I recorded of what happened accurately depicts the events leading up to the agents shooting him and several minutes afterwards. The video is attached as Exhibit 1.
16. I have read the statement from DHS about what happened and it is wrong. The man did not approach the agents with a gun. He approached them with a camera. He was just trying to help a woman get up and they took him to the ground.
17. I feel afraid. Only hours have passed since they shot a man right in front me and I don't feel like I can go home because I heard agents were looking for me. I don't know what the agents will do when they find me. I do know that they're not telling the truth about what happened. I've heard that other witnesses might have been arrested and taken to the Whipple Building.
18. I am disgusted and gutted at how they are treating my neighbors and my state. I keep alternating between crying and feeling determined it is important to remember the value of documenting injustice. We show up for the people who need us to bearwitness, because it can't just be one group of people bearing the brunt of their tyranny. This is a struggle to protect our freedom and democracy, those things are on the line. He lost his life for those values.
I declare under penalty of perjury that everything I have stated in this document is true and correct.

Dated and signed on Jan 24, 2026 in Hennepin County, State of Minnesota.

Filming federal agents in public is not a crime, nobody should be harassed or restrained for doing so, nobody should have their phone confiscated for it, and nobody should get the death penalty for it. This is supposed to be a free Republic, not an authoritarian police state.

There's a reason protests are also called demonstrations. Because they are how we show who we are, what we believe, and why we act. When orchestrated well, they allow us to take our rightful moral high ground - making it more difficult for the enemy to succeed in attack.

Statement from the entire Minneapolis City Council in support of a General Strike and Day of Truth & Freedom on January 23rd.
"Minnesota is deeply grounded in the values of community, compassion, dignity, and solidarity. The violent actions of federal agents have had profound effects on families and communities across our city and state, creating an environment of chaos, fear, and disruption in our neighborhoods. This federal operation has made life difficult for many residents to shop for groceries, go to work, take their children to school, or keep their small businesses open. When residents are brutalized and profiled, families are torn apart, and children are arrested, our communities are not any safer. We continue to demand that ICE, and all federal agents leave our state immediately. Minnesotans have a long tradition of activism, protest, and civic engagement during significant inflection moments in our state. A broad coalition of labor organizations, faith communities, community-based organizations, students, small businesses, and workers have called for a statewide Day of Truth and Freedom as a time for solidarity, community, mutual aid, and protest. The Minneapolis City Council fully supports this action as a time to exercise your constitutional rights, to express support for our neighbors, and demand the end of this federal occupation. We acknowledge and respect the diverse ways individuals, families, essential workers, students, and businesses may choose to observe this day and support our community.
Together, with our community, the City Council reaffirms our commitment to civic expression, community safety, and our immigrant neighbors. We will continue the work of ensuring justice, freedom, and dignity for all during and beyond this occupation."
