Assembly Bill 1056 aims to enhance firearm regulations, improve victim and witness protections, and redefine obstructing justice in Wisconsin. The bill mandates that all firearm transfers must occur through federally licensed dealers and require background checks, with specific exceptions for certain transfers. It introduces an extreme risk protection order process, allowing law enforcement or family members to petition for a temporary restraining order against individuals deemed likely to harm themselves or others with a firearm. Additionally, the bill increases penalties for illegal firearm possession and straw purchases, and prohibits the manufacture and possession of undetectable firearms.

In terms of victim and witness protections, the bill increases funding for crime victim services and modifies reimbursement structures for counties providing these services. It raises penalties for witness intimidation and establishes new funding for the address confidentiality program for victims of domestic abuse. The bill also redefines obstructing justice to encompass a broader range of actions that interfere with legal investigations, increasing the penalties for such offenses. Overall, Assembly Bill 1056 seeks to strengthen public safety measures and support for victims while enhancing law enforcement capabilities.
