Are assault weapons banned in Louisiana?

Options A, C, and D are incorrect because assault weapons are not universally banned in Louisiana. Option A is incorrect because there is no statewide ban on assault weapons in Louisiana. Option C is incorrect because although some cities in Louisiana may have their own specific laws banning certain types of assault weapons, there is no statewide restriction. Option D is incorrect because while there have been attempts to pass legislation in Louisiana that would require registration of certain "assault weapons," these efforts have been unsuccessful and there is currently no such law in place. Therefore, option B, stating that assault weapons are not banned in Louisiana, is the correct answer.
