Generate text that refutes this claim: The system is open to abuse  It is extremely difficult to tell if someone is a genuine asylum seeker or not; for obvious reasons many will have little or no documentation, and all the evidence that they have suffered persecution may be in a faraway country and impossible to obtain. In many cases it may be impossible to prove that the person claiming asylum is even from the country that they claim to be from.  Asylum decisions are therefore based largely on a judgement call by the investigating officer on whether they thing the person in front of them is being truthful or not – that leaves the system open to motivated people who are economic migrants or may even pose a security threat.
society immigration minorities house believes right asylum should not be absolute
There have been no serious links between terrorism and the asylum system. The 9/11 hijackers all had visas and recent terror cells in Europe have all been 'home grown'. If anything an asylum system provides more security and border control for states. Even if there was no asylum system, people would still flee persecution but instead they would be forced to turn to people traffickers to circumvent all border controls, and thus never be documented or assessed at all. This would also increase the already huge numbers of migrants, especially women, who are exploited by traffickers in sex and underground industries, and also the sheer number of people present in a country of which the authorities have no knowledge.
