I stand (I’m sitting) corrected. If he keeps his rights, he did the right thing.
Understandable mistake. Thousands of men have unknowingly surrendered their 2A rights by signing an agreement to avoid court when accused of domestic violence. Only later do learn how the Lautenberg Amendment unconstitutionally strips their rights without even having a conviction, and sometimes not even being arrested or charged. In some "May Issue" states, this plea deal would be a problem, but Wisconsin is "Shall Issue".
