concurring:
I fully concur in the opinion of the court except to the extent that it may be read to imply that a warrantless arrest or search may be effected in a private residence without the concurrence of both probable cause and exigent circumstances or that the facts shown would warrant a finding that the building in this case was a “public” building. While I do not read the opinion as going that far, I wish to emphasize my understanding in this regard, since it forms the basis of my concurrence.
