The 4th Amendment of the United States Constitution protects against unreasonable searches.  A warrantless search is per se unreasonable for constitutional purposes.  Unless there is an applicable exception to the warrant requirement or there is the presence of probable cause and exigent circumstances, the warrantless search is illegal and unconstitutional.

Those who have been subject to a warrantless search should immediately speak with a criminal defense attorney, so he can evaluate the facts surrounding the search and determine whether the person’s rights have been infringed.
