In a way these threads are almost pointless with cyclical arguments that are never satisfactorily concluded for either side. I suppose in a way the same can be said for 99% of conversations we have as humans!
There are scummy horrible disgusting people of all colours/religions/beliefs/nationalities carrying out low level to high level disgusting and horrific stuff on other people. Of course there's a debate to be had around whether or not certain alleged/actual crimes here in the UK haven't been fully investigated due to the nationality of the alleged/actual perpetrators. However to assert any one group of people is worse than other groups is quite frankly stupid.
I've said before in threads like this, the authorities should investigate everyone equally and if convicted, everyone should face the same degree of sentencing.
And if we're going to go down the 'who's worse' route, we need to remember for centuries past and perhaps to the present day in some quarters, the 'white man' carried out horrendous stuff right left and centre across the globe and faced little if any legal consequence.
