<i>At the risk of stating the painfully obvious, &quot;gun crimes&quot; refers to crimes committed with guns (murder, assault with a deadly weapon, armed robbery, etc.), not to violations of gun prohibition.</i><p>In that case, one could argue that &quot;drug crime&quot; isn&#x27;t really violation of prohibition laws but the crimes committed to feed the habits of addicts or crimes committed while under the influence of drugs.<p>In reality it&#x27;s both. Gun crimes are shootings and non-violent violations of firearms regulations. Possession of an unlicensed machinegun is a gun crime.
