Animal torture is an unconscionable crime that shouldn’t be tolerated at the federal level. Criminalizing this horrific crime at the federal level will make it easier to prosecute, and will bring federal law in line with state laws, which universally criminalize animal torture.
Since animal torture is already illegal in all fifty states, there’s no need for an additional federal law criminalizing it. When these cases cross state lines, prosecutors can work together to determine which jurisdiction the crime occurred in, and prosecute accordingly.
