I fail to see why the targets of this move, the gangs of scum that hang around the outskirts of UK cities having their recruitment videos taken down is such a bad thing.
These videos show hooded/masked youths, bragging about their violent crimes, and showing off their hoards of stolen/black-market guns and knives.
Taking down the recruitment videos helps to stop the gangs growing, it's part of a wider tactic police here use to disrupt the social lives of the gangs, forcing them apart.
Of course, if you'd rather the scum of the British underclass were allowed to rob, stab shoot, and deal drugs freely, you're welcome to take them, and let them do so in your own country.
We're sick of it here, especially in Liverpool.
