It is a provocative message: Eliminate jails - take no prisoners.
The message is even more stark with a picture of a rifle between the words.
The message appears on T-shirts being sold by Sensible Stuff, the commercial wing of the Sensible Sentencing Trust.
Director Ron Bishop said the message did not reflect the trust's policy but was intended to get conversation going about law and order issues. Another T-shirt featured a statement suggesting prisoners be made to break rocks.
Bishop became involved in the trust after his son Dean Browne was beaten to death with a hammer in 2010. Mikhail Pandey-Johnson and Karl Nuku were convicted and are serving life sentences.
