A valid argument for the Trump policy is that for the last 4 years the border has been open allowing these violent gangs to enter and expand their influence. Not only that but the Biden admin and many other governments had a sort of anarcho-tyranny. Refusing to enforce laws on the books and protect the people and at the same time prosecuting people that tried to defend themselves and their property.

I'm sympathetic to this position. I just don't believe the approach being taken will solve the underlying problem, in addition to it violating the rights of those caught in the dragnet.

The solution isn't a new idea. If you wanna stop the drug gangs you decriminalize drugs. Cut off their funding source. Coupled with removing the welfare state this would drastically decrease illegal immigration.
