They are war criminals having murdered and raped unarmed innocents in Syria so must be tried in the country of their crime, and by the legal system of that country.

I spent a couple of hours early this morning with some heavy equipment operators on a building site. They are all Irish, men and women, in their twenties and highly skilled and willing workers they are too and not shabby in their communication either. A pleasure to work with and while we are pleased to welcome the new one who arrive, we are sad to lose those who return home, often via some other travel.

I related those facts to prove, unnecessarily as it would be to anyone in construction but it would obviously be news to some here, that there are many young men and women in countries such as Ireland, Germany and so on who do not only want to work here for a contracted period, but would move permanently if offered. They are young, highly skilled, want to work and can provide unblemished records of good citizenship.

There is a proactive solution to the imported problem of racial hatreds, centuries-long ethnic wars, toxic political systems, values and traditions (remember Rotherham!) and that is to manage the risk by preferring the most suitable and best migrants in the first place.

The federal government, both sides, know that already. They have always known it. So what prevents the feds from:

1. reeling back the migration numbers, to well within the range that does not carry any risk of destroying the character and culture of Australia that is prized by us and is applauded around the world (but NOT by some migrants!) and are within conservative estimates of infrastructure growth and supply of energy, water and other necessities; and.

2. since it is a buyer's market for a peaceful, democratic, developed country like Australia, prefer the most suitable, best and brightest migration applications?

Some here seem to be so preoccupied with rubbing Australia's nose in the diversity-our-arrogant-feds-force-us-to-have (to improve Labor's and Greens' electoral prospects in marginal ethnic seats) that they bend over backwards to allow every possible excuse, leeway and leniency for scum who coldly, deliberately and covertly joined and supported ISIS.

Josephus, are we sure that this obviously nasty Isis fighter's wife and kids raped and killed others while overseas?
Should they be punished for what he did?
Are we sure they were not merely his pawns in all this?

He is obviously a very violent person that I doubt his family would want to upset or disagree with.
I am not comfortable with maybe condemning innocent people...

Of course these grubs should not be allowed back into Australia. They hate us and our way of life. It is hoped that Abbott means what he says this time, and strips citizenship from these scum and all like them. What they have done is illegal, and they are not needed here to bludge off us.

Someone who assists another 1) who has committed a felony, 2) after the person has committed the felony, 3) with knowledge that the person committed the felony, and 4) with the intent to help the person avoid arrest or punishment. An accessory after the fact may be held liable for, inter alia, obstruction of justice.

If nothing else I would suggest there is a strong case against Sharrouf's wife for being an accessary after the fact, and/or an being an accomplice to his crimes.

I agree that being Sharrouf's wife probably includes little say in family decisions but when you lay down with dogs you wake up with flies. Once those kids were dressed in camouflage army suits, handed AK-47's and allowed to hold with lopped heads, in my view they graduated to mini-terrorists.

We don't need this family back in Australia, so why would anyone even entertain the idea?

"ISIS fighter", huh? Terrorist and callous killer would be more suitable.

How did his wife and family end up over there without the cooperation of his wife?

What does it take to flee to safety with your children when in an international airline terminal in Australia? -Where even the slightest nervous look results in close observation by plainclothes and uniformed security, airlines staff and other official and private employees in an airport. Look for a bit longer at security cameras or watching security and help is by your side instantly.

Australian authorities are now being forced to react to difficult problems that will never go away and will be enormously expensive.

All because federal governments have NOT exercised due care and diligence in screening for and giving preference to, the most suitable migrants.

Instead, federal governments have allowed the diversity idealism tail to wag the larger immigration policy dog. Federal governments are there only on the approval and sufferance of the public and they need to remember that they are the servants, not the other way around.

Australia has been dealt dreadful cards by deeply flawed Liberal and Labor PMs like Malcolm Fraser and Kevin Rudd, whose personal ambitions on the international stage, sheer arrogance and refusal to take advice resulted in decisions that continue to hamper and imperil Australia, from within and from outside.
