No, you're making the argument of a frame-up artist. There had been burglaries in the area, and he did go over to the building site and look around. However, this by itself, as any lawyer would tell you, would not justify a citizen's arrest.
If they had really wanted to catch him stealing, they would have left something valuable at that site, and video'd him stealing it. Since he was a frequent jogger, they could then have arranged to have him arrested next time, assuming his face was not identifiable from the video. (I don't know if his previous conviction meant his photo was on file.)
If they had just wanted to kill this kid, they could easily have ambushed him from a distance. It would just be another unsolved murder, probably put down by the police to yet another Black-on-Black crime (the huge majority of Blacks who are killed are killed by other Blacks), probably a dispute over a woman or who gets to sell the dope on a certain street corner.
They wouldn't have video'd what they did, they wouldn't have called the police.
They didn't know the law. They were not smart. But most of us don't know the law. Most of us are not 'smart' about many important things.
That's why patriots, if any are reading this, need an organization. Organizations let not-smart people act like smart people, because we can find smart people (lawyers, policemen, doctors, electricians, combat vets) to advise us.
Right now, we have no viable national organization. The Three Percenters and the Oath Keepers were not up to the job. (That's a long story, but the conclusion is clear.)
So we have to start locally. A good place to look for advice on how to approach this can be found here: [
YCPT ] -- and the Houston branch of the Texas State Militia show how to do 'outreach work' (and I don't mean reaching out and touching somebody by proper adjustment of windage and elevation, although that's important to learn as well). [
