The left has been actively importing criminals in order to change congressional representation & reshape voting districts. They have also been actively manufacturing problems that historically make people demand govt solutions (facilitating & subsidizing drug use, legalizing theft, etc).

These are serious issues, so people on the right are not wrong for wanting these issues addressed.

The Trump admin's effort to address these problems has been to create an unaccountable federal police force which doesn't have to show badges or follow any of the basic protocols for making arrests. And like most self serving human beings, ICE agents appear to prefer pursuit of peaceful & productive human beings as opposed to violent gang members who might actually harm them. There are no quotas or controls that are likely to be effective in changing the way any coercively funded paramilitary force is going to behave.

The only real solution to the immigration problem is to eliminate the social programs that attract parasites & criminals, while removing the taxes & controls that repel the intelligent & productive.

The only way the govt can solve the problems the govt created is to get out of the way. Unfortunately, that is unlikely.
