What seems like common sense on the surface is actually more complicated in practice. Australia follows this approach, and New Zealand often ends up on the receiving end (>15,000 prisoners in the last 10 years) for everything to fraud to traffic offences.
NZ and Australia have a common travel area, somewhat like the EU, but with fewer rights. Under current policies, anyone with an NZ passport who commits a crime in Australia can be deported back to NZ. The issue is that many of these individuals have no real ties to NZâthey may have been born there while their mother was on holiday (There a literally examples of this) but have lived their entire lives in Australia. Yet, they are now being sent âhomeâ to a country they donât know. This creates a situation where NZ is forced to take in people who, in every meaningful way, are Australian.30 or 40 years since being a kid. Ties to Australian gangs. A product of the failures of the Australian system.
There are many people in the UK that were born abroad (nearly 20%), but for many in every meaningful way they are British. They perhaps only speak English, they only know the country they were born in from stories from their parents. Perhaps only visited Jamaica, Germany or India on holiday. Imagine if those countries start reciprocating. Imagine if Ireland or the rest of Europe started deporting anyone with a British passport back to the UK if they commit a crime ? Its becomes a tit for tat similar to what we are seeing with Trump with tariffs.
Alternatively how would you feel, if your family member was attacked. The offender is deported. Only problem is in their country the offence is not considered a crime. Perhaps age of consent is a young teenager. Perhaps its part of their religion or culture that we would find offence. They could get deported an serve no time. In some cases they could even be celebrated. Would that be justice ?
