"He also intends introducing at least seven big bills dealing with violent offenders, criminal gangs and youth crime, DNA testing for every person arrested for an imprisonable offence and increased police powers to protect domestic violence victims."
Yes, you read it. DNA testing for every person arrested for an imprisonable offence, whether guilty or not.
ACT's website has no recent press release on this, but it does have them from 2004 and 2002. Then ACT supported having a DNA database for all convicted criminals, any taken from suspects who are cleared should be destroyed.
I'd like to know what ACT policy is now. I know Libertarianz would categorically reject a database of DNA from people who are not convicted who did not consent to it.
