They can’t take what they can’t find ;-)
Ditto.
Back in the day, you were’t a felon until you were actually convicted. Maybe just the accusation is enough now. Or will they take your weapons (if you actually had any) until the case is decided. But then according to the anti’s just the fact that you would ever consider having a firearm could be grounds to have you adjudicated as having “mental issues”. What person in their “right” mind would ever want one of those?
If the feds want to dredge ‘em up out of the lake, that’s their business...
