I grabbed her and dragged her out of there just as there was a violent eruption of flame.
She'd been dead otherwise.
I never once thought I had made an unlawful entry. Now, if I'd been a cop or a fireman would the law have looked at that action differently and counseled them to stand aside until the fire died down and they had a warrant. After all it is unreasonable to dash into a fire to save someone's life.
The Fourth Amendment addresses searching someone's home and personal effects looking for evidence of a crime. Is that what you were doing there?
