The suggestion up thread was that if people knew police could randomly come and search houses these things would maybe stop happening. I said that would never happen in the US because of our constitution.
LE can not search without cause in the case of a crime they can ask to search but they have to have just cause to do so without consent. .
I don't see why police would even need to search random houses in this case, when suspect's daughter was one of the last people to see Gina before Gina went missing. Sounds like police could have just searched suspect's house and save everybody a lot of grief.
