Due process costs money, a lot of money.

El Salvador had to compromise on due process when they rounded up the gang members. When 1% of your population are murderous , violent, criminals who need to be locked up, there simply aren't enough judges or lawyers to give everyone full due process.

The West faces the exact same problem with illegals. We've allowed in literally tens of millions of violent, unproductive, people who need to be forced out, and fast. There aren't enough judges or lawyers on the planet to give every one of those people trials.

The compromise is some innocent people will be wronged. But overall it's the right compromise to make. Fighting violence and criminality at this scale is closer to fighting a war than it is a policing action.
