I don't see how people shooting other people, robbing, looting, etc... is federal. The guy handing guns out of his trunk is federal, no doubt. But the rest of it does not seem federal at all. If a gun used in a shooting was proven to be out of the trunk of dude's car, yes, but otherwise, no. Proving a gun was out of the back of the dude's car is another problem since no one knows anything about those guns (ie. serial numbers, origins, things like that). Certainly someone could get arrested and then say they obtained the firearm from some dude out of his trunk, but again, then that would have to be proven, not assumed.
I might need to look up the Lindberg kidnapping, as I have no recollection about it, and to be perfectly honest, I've never even heard of it. We do have a Lindberg Airport here in San Diego though, so I've got that going for me. I also stayed at a Holiday Inn Express last night, sot hat was nice.
