"The complainant remains anaonymous and the fire arms owner has to apply to get them back. Very expensive and time consuming."

IOW, the constitutional guarantee of "innocent until proven guilty" is inverted into "guilty until you prove yourself innocent". Red flag violates many more than one constitutional right.
