I'll let the lawyers argue that, presuming it was an unsecured construction site, an uninhabited future dwelling, the entry was unauthorized. If you've read the owners comments, that's far from clear. He knew about the "unauthorized" entries but didn't contact authorities about them though he did put up a camera. Then there's intent to commit a felony or theft therein. There's nothing to indicate he was committing a felony. I think the McMichael's may have some problems establishing burglary. Which might not be the only action authorizing a citizen's arrest. Personally, I think their actions were stupid. Whether they were legal will depend largely on the legality of the "arrest"/detention. We'll see.

Lol, “authorization” can’t be granted after the fact. They’ve already stated they didn’t know him, so any legal authorization didn’t come from the homeowners.

Sad to disappoint. The home under const will not be allowed as evidence.
Vigilatee is not and was not a law enforcement officer.Maybe thought he was and that was his 1st mistake
All that will be allowed is a man with a loaded gun initiated a confrontation on a public st.
When the deceased tried to defend himself how ever he felt necessary he was shot to dead while the shooters accompliss was standing by as back up.

Fire up ole sparky.
