Kanter pleaded guilty to mail fraud, 18 U.S.C. 1341, based on his submission of bills to Medicare for non-compliant therapeutic shoes and shoe inserts. Due to his felony conviction, he is prohibited from possessing a firearm under both federal and Wisconsin law, 18 U.S.C. 922(g)(1) and Wis. Stat. 941.29(1m). He challenged those felon dispossession statutes under the Second Amendment, as applied to nonviolent offenders. The Seventh Circuit affirmed judgment upholding the laws. Even if felons are entitled to Second Amendment protection, so that Kanter could bring an as-applied challenge, the government met its burden of establishing that the felon dispossession statutes are substantially related to an important government interest in preventing gun violence. Congress and the Wisconsin legislature are entitled to categorically disqualify all felons—even nonviolent felons like Kanter—because both have found that such individuals are more likely to abuse firearms. The “bright line categorical approach … allows for uniform application and ease of administration.”
