"give up more and more freedom and the courts seem willing to help it happen in the name of social justice, political correctness or even the judge's personal feelings... "
I think the judgment in the article refutes your opinion. Nobody has giving up or lost any of their constitutional rights. Even child pornographers still have their rights. If the suspects in this case are guilty the law enforcement agencies will just have to find and rely on other evidence to prosecute the offenders. If that isn't possible then the suspected child pornographer is free to go on their merry way. Maybe some more evidence will be found after their next offense.
