There is no good reason for legal assault weapons

This seems like a no-brainer, but apparently not to people with no brains. We had a ban on them before and it reduced mass shootings. It's apparent that outside the military, which uses such weapons for efficient mass death, there is no use for them in civilian society other than mass killings. That's a bad reason. We do not have the 'freedom' to kill each other. We must do what's necessary to ban them again if we ever hope to reduce the senseless murder of our citizens.
