I'm sure the penalties require a clear and convincing standard opposed to the accused. Did you notice the 2 1/2 year - instant Federally Prohibited Person; that is the goal of all laws now - more PP.
While the confiscating of one's guns on'y requires a "preponderance of the evidence", filing a false ERPO is a criminal offense, therefore requiring it to be proven beyond a reasonable doubt for them to incur any penalties.
