Fingerprinting people entering and leaving the country?

As the thread title says, should people be fingerprinted upon entering and leaving the country, regardless of citizenship?

Here are my reasons.

Criminals who (are presumably fingerprinted by police by electronic means) will be seen leaving the country if they are remanded on bail, although their passport is often seized during this, they could easily flee to the UK with a driving license, other ID, or if they are citizens of other countries, they can use another passport.

If a person is wanted in Ireland (for, just say, child maintenance reasons), when they re-enter Ireland they will be apprehended when their fingerprints "set off alarm bells".

If someone is suspicially entering and leaving the country they can easily be tracked.

This can also be used to prevent identity theft, illegal immigration and welfare fraud (say, people wh might be claiming welfare in Timbuktu and back in Ireland).

In case someone loses or "loses" their passport or ID in transit, they can merely scan their fingerprint and their photo will come up on screen.

If a dossier is kept of every Irish citzen's fingerprints of foreigners' fingerprints (inlcuding British) in Ireland, if a crime is commited, then the perpetrator can quickly, efficiently and easily be tracked.

I am aware that the open border with NI will pose a problem, if the UK don't impose such border restrictions on people then they can easily fly to Belfast and then get the train / bus / car to the Republic, unless we keep a dossier with the UK.

So what do y'all think.

An in before someone just responds with "NO" or the PC brigade and Liberals responding with "it's an invasion of our privacy".

So, Discuss.
