I do not recommend this Malmgren interview.
I think this interview was a psyop to reinforce the propaganda of benevolent space bros looking out for bad humans destroying other humans. They really show their hand in the last 10-15 minutes of the interview. I could hardly believe the ignorance of Jesse and Malmgren's daughter when they said UFOs have never shot at humans. I'm sure Malmgren himself knew better and was playing along in getting the disinformation out regarding UFOs having humanity's best interests. Come to think of it, the idea that an alien would tell people how to harm the alien's UFOs by using nuclear explosions and xrays is laughable. As if 4D STS would tell us how to harm them. The interview is all entertainment and no substance. No substance of aliens kidnapping, killing, and eating people, no substance of aliens with demonic or vampiric attributes. The interview is pretty much nuts and bolts with a little sprinkling of mild paranormal telepathy and time travel.
Malmgren dying shortly after the interview might be part of the old setup of getting people to believe the disinformation because they can't believe the person would be killed to get the disinformation out there. I seem to remember an example of this in the Wave with the UFO investigator found dead in his car.
