Justice Secretary Kenny MacAskill has unveiled SNP plans to tackle crime in Scotland if the party is re-elected in May.
Mr MacAskill said the SNP would push for more reform of rape laws and Serious and Organised Crime Prevention Orders would be introduced to stop crime bosses running businesses.
Those who breached the civil orders could face criminal charges and be jailed for up to five years.
Under SNP plans for reforming rape laws judges could direct juries to disregard evidence of a delay in reporting the rape or a lack of resistance from a victim in cases.
Mr MacAskill said: "Rape is a horrific crime, and we must do everything we can to ensure those guilty of such despicable offences are brought to justice.
"The SNP government has already done a lot to bring Scotland's sex crime laws up to date, but the fact remains that Scotland's conviction rate for rape is still low in comparison with other European countries.
"Our plans will mean that those accused of rape will no longer be able to use any perceived delay in reporting a rape or supposed lack of resistance from a victim as part of their defence."
Mr MacAskill also said a re-elected SNP government would work with the UK Government to establish a ballistics "DNA" database, which would allow fired bullets to be matched up to guns.
He said: "Gun crime is a serious and tragic problem. The creation of a ballistics DNA database would boost policing intelligence about who buys guns used to commit crime, and therefore help deter gun use and better enable the criminals to be lifted and punished," he added.
On organised crime, he said the SNP would "clamp down on crooks" if voted back into power.
He said: "No-one involved in organised crime at any level should be allowed to get away with it. A re-elected SNP government will clamp down on crooks.
"Serious and Organised Crime Prevention Orders work in Northern Ireland and they will work for Scotland. Where police and the courts have good reason to believe someone will use business to engage in criminal activities we will take steps to restrict their actions.
"Too often there is suspicion over taxi firms, tanning salons, security firms, and even nurseries. Putting prevention orders on individuals the courts know are involved in criminal activities will help to keep those industries free from organised crime, cut their ability to make criminal cash off the back of ordinary Scots and make our communities safer."
He also said a rre-elected SNP Government would tackle under-age drinking.
He said: "It makes no sense at all that adults can buy booze for youngsters and escape punishment simply because the drinking takes place in public.
"That is a legal loophole that must be closed, and the SNP will take firm action to do so."
