you say they are different? they re very different. this is exactly the same question our great grandfathers faced in 1934 when they were in the congress. gangster-type weapons, that s what the law says, the weapons killers and using, mostly they were killing other gangsters like the st. have h valentine s day massacre, but they weren t killing police officers like the kansas city station. we used to have these old search warrants and arrest warrants from back in the 30s when they were doing these shootings, and those were machine guns coming in after the first world war. congress said, hey, these are military guns, they shouldn t be in public hands. so we re going to make laws that restrict them. those laws that restricted them really controlled those weapons for 50, 60 years, and he rarely ever saw a registered submachine gun used in a crime.
