And in addition, we need to amend the law to reduce/remove the litany of objections/obstacles to removals. Dublin was not the answer - rarely enforced because the immigration "industry" made it so difficult to do so.
The migrants keep coming because they perceive - correctly - that once here, they'll never be removed. Patel is trying to do something with the new bill to improve the situation, but is being fought tooth and nail by the "industry". In fairness, there need to be checks and balances against state overreach, but they need to be based in some form of logic rather than the pure theoretical they are now.
The other thing which is often omitted in the debate is that if the migration continues unabated, the source countries become ever more untenable.
