Finding some precedents doesn't address the major changes. Do you really dispute there have been major changes in executive branch behavior?
> Wait till you hear about a kid named Elian Gonzalez
Elian's mother died at sea, trying to reach the US from Cuba with Elian. Elian's father sought to bring the child back to Cuba, but an uncle in Miami refused to surrender custody. Obviously, barring something unusual, a father has custody of their child and the INS, courts, and Department of Justice agreed. There was an extensive legal process and also mediation.
It became a partisan political issue and after all that the uncle still refused to surrender Elian. Law enforcement forcibly removed the child and gave custody to the father.
I don't see how that is related to the current warrantless home invasion policy.
