So illegal crossings are ok with you?
Of course not. But I haven't seen many plane or boat hijackings taking place recently, have you? So there are hardly any actually happening.
why don't they go through the official route or seek asylum in the first country ?
Because the rules don't work the way you think they do. If they have a support network (e.g. family) then the rules allow them to travel further.
I'll tell you why it's because most our poncing parasites ,men aged between ages of 18 /30 prepared to run off on arrival hoping to never be seen again put up in hotels and B&B at the tax payers expense they offer nothing ,you're a joker !
