Actually in practice you pretty much CAN!
As a gun dealer I met several victims of this.
Ex makes a call to the cops, cops then “Exercise due caution” to immediately confiscate all firearms*.
The firearm owner then gets to TRY to object in court at great expense, while laboring under the presumption of guilt.
Judges tend to ignore or not even allow introduction of exculpatory evidence, on par with “The Reign of Terror” as practiced during the French revolution.
*Refusal to open your safe to allow the confiscation will get you charged with things like “Failure to heed a police officer”, “Assault on a police officer”, “Trespass” (In your own home!), etc.
Same thing. Cite me the statute (be specific) that does what you claim (phone call and seizure with nothing more).
