It is the ONLY legal way for the authorities to gain entrance to
private
property without some sort of exigent emergency situation existing...


There are other ways:
1. Permission of the owner or someone the authorities believe is acting as
the owner's agent.
2. If the property is abandoned, looks abandoned, or looks like it should be
abandoned (the last applies to most trailer houses).

Remember, the 4th Amendment prohibits only "unreasonable" searches. You can
be searched at airports, points of entry, "stop and frisk" (Terry stops),
and so on. Further, there is no LAW against an unlawful search; the only
sanction is that anything found can't be used against you.
