Failure of enforcement, is not a signal that US politics are broken, as much as a niche inconsistency. There's plenty of enforcement that is not occurring today, due to pure corruption. The US electorate has failed to hold politicians accountable for over 150 years. Again, this is largely because of a 2 party system that only selects for oligarch-directed interests. Most of it (like how immigration law is enforced) is performative. This administration has laid it bare.
And the hyperbole doesn’t help. Federal law enforcement is not “kidnapping” anyone, they are detaining them as is their power under immigration laws.
And if they didn’t get doxxed they wouldn’t need masks.
It’s fine if you want open borders, but your hyperbole makes it hard to take your arguments seriously.
It's also worth considering, if masked secret police weren't kidnapping* and killing people in the streets, including citizens, then state governments wouldn't be trying to identify them as suspects in a crime and hold them accountable for their crimes (or "dox" them as you so hyperbolously put it).
Rodrigo Duterte is currently being held for trial in international court for doing with his security forces what donald is currently doing with his, both perpetrators claiming it's all in the name of law and order, fighting crime, etc. Food for thought.
* Yes, kidnapping: countless court rulings have found that ICE did not have any legal basis to arrest, detain, or attack the bystanders who were arrested, detained, and/or attacked. ICE's criminal court cases have mostly fallen apart or been dropped due to this.
