He's a former military contractor
No he's not. He claimed to be an army veteran, but The Pentagon has confirmed they have no record of anyone by his name listed as ever serving.
There is no evidence he was ever a military contractor, either.
has that weird tattoo on his neck
Probably a mid-life crisis. Before IG/FB nukes his profiles, you could see the tattoo was less than a year old.
was arrested for having a loaded gun at a previous protest in Portland but all charges we're dropped...
That is because the local D.A. is as feckless as the mayor. State Police were federally deputized which is why there is now a steady stream of federal charges being filed against suspects in Portland.
