They're not genuine asylum seekers because they are entering the country illegally, also having already passed through other safe havens.
I didn't mention the term economic migrants, you did. As you mention it though, the reality is that amongst the people illegally entering the country some will be fleeing war zones and political oppression, some will be criminals, some terrorists and some economic migrants. That's why it is important that we have a robust and transparent system, so we can sort out genuine from nefarious cases.
You can argue we don't have that or at least not in a format that you would personally like it to be; but illegal human trafficking certainly is not the answer and is more barbaric than anything our government has either in place or failed to put in place.
Out of interest, do you support a system that encourages human trafficking, exploitation, abuse and in extreme cases manslaughter of it's 'clients' whilst providing millions of pounds for organised criminals, as it appears to me that you do?
Don't you want to see systems put in place that shut human trafficking down whilst simultaneously lobbying for a system that more suits your views on immigration? Or is it the case that if your expectations on legal immigration and asylum aren't being met you are happy for the human exploitation criminals to continue their work regardless?
