If those suspected illegal activities (remember innocent until proven guilty and probable cause) are not putting an innocent persons life in immediate danger then no there is no justification for kicking in the door. The police should be required to get a search warrant, announce their presence and wait for a response. If no innocent life is in peril there is zero justification for forced entry and certainly no justification for deadly force which at this point is one in the same.
Are you making the assumption since you own the property this legitimizes the use of forced entry?
A great many American homes are actually "owned" by a bank or mortgage company that holds the mortgage. Can you imagine a bank making the same request?
Ownership of the subject property really has nothing to do with justification for forced entry.
